2005: Well, that's it from me. Thank you for your contributions. There will be match reaction to follow and please join us again for this weekend's Scottish Premier League live coverage.
"Rangers are dogs of war and got to the final like this a few years ago. They looked down and out and needed a lift from somewhere and got that tonight." BBC Radio Scotland pundit Billy Dodds
1956: Rangers win on away goals to progress to the last 16 of the Europa League. The Ibrox side will face PSV Eindhoven in the next round, the Dutch side having triumphed 5-3 on aggregate against Lille.
Rangers level the tie and are now ahead on away goals. Healy crosses for Maurice Edu to tap home in the six-yard box. If the score stays the same, Rangers will progress.
1951: GOAL Sporting 2-2 Rangers (Edu)
1949: There will be four minutes of added time in Lisbon.
1948: Rangers are inches away from an equaliser. Vladimir Weiss's terrific cross just misses Kyle Lafferty in the six-yard box.
1947: Sporting almost score again. Yannick Djalo opens up the space for Carlos Saleiro but the substitute's shot is short of the near post.
1945: Extra-time is now off the menu as Rangers will progress if they get another away goal to level the aggregate score but with only a few minutes left, Sporting will fancy their chances of seeing out a win.
"It is a bad goal to lose. Bartley gave the ball to Papac and he lost the ball and Yannick was unmarked at the back post." BBC Radio Scotland pundit Gordon Smith
Rangers are caught cold as Joao Pereira crosses for the leaping Yannick Djalo heads past Allan McGregor. Sasa Papac had conceded possession just before Pereira got his cross away.
1941: GOAL Sporting 2-1 Rangers (Djalo)
1941: Both scorers have now been substituted.
1940: Steven Davis fired a shot over the Sporting bar moments ago and Rangers are about to bring on David Healy from the bench, El Hadji Diouf being withdrawn.
1939: Pedro Medes's game is over, he is being replaced by Carlos Saleiro.
1938: El Hadji Diouf leads a Rangers charge on the counter-attack and his cross is diverted out for a corner before Kyle Lafferty can get a shot in.
1937: Sporting scorer Pedro Mendes has pulled up with an injury and has gone off for treatment.
From andset1191 by twitter #bbcsportsound:"Interesting change from Rangers to bring off Davie Weir, credit for Rangers for going for it, but nervy stuff for the fans!"
"It is a very brave move to make and you must give credit to the Rangers management team for making such an attacking move away from home in Europe." BBC Radio Scotland pundit Gordon Smith
"I can't remember David Weir ever coming off for Rangers." BBC Radio Scotland reporter Chick Young
1929: Rangers are making a couple of substitutions. Captain David Weir, who was struggling with illness prior to kick-off, and John Fleck are withdrawn and on come Kyle Lafferty and Vladimir Weiss.
1927: Yannick Djalo weaves way past two Rangers defenders but Ricky Foster's last-ditch tackle carries the ball out for a Sporting corner.
1926: Rangers win a free-kick shooting distance from goal but Steven Whittaker's strike sails over.
1924: Sporting struggle to defend a Rangers corner but Kyle Bartley, Maurice Edu and then Madjid Bougherra cannot get in a clean effort at goal.
1922: Fantastic action at both ends there. First, Steven Davis heads into the arms of Rui Patricio after meeting El Hadji Diouf's cross and then Sporting break away and Joao Pereira forces Allan McGregor into an excellent save.
1920: Rangers break quickly after soaking up a bit of pressure but John Fleck's eventual delivery into the Sporting box drifts out for a goal kick.
1917: Rangers midfielder Maurice Edu is cautioned for catching Abel late.
"Rangers have got to get out and press further up the field. The chances will come on the break as Sporting are pressing." BBC Radio Scotland pundit Gordon Smith
1915: Sporting miss a great chance to go in front. Pedro Mendes floats a cross into the box and Jaoa Pereira ghosts in unmarked to get in a header that loops over the crossbar.
From David in Shetland by text on 80295: "Seems to be a pattern forming in the way Rangers go about games. Is the defensive attitude being shown up for what it is, amongst a poor shower of players?"
1908: Matias Fernandez's whipped free-kick forces Rangers goalkeeper Allan McGregor to tip the ball out for a corner. A good save by the stopper.
1905: There have been no changes to either side at the break.
1904: Sporting kick off the second half against Rangers.
1903: As we wait for the second half to get underway. Lille are leading PSV Eindhoven 1-0 on the night in the Netherlands and 3-2 on aggregate. The winner of that tie will play the winner of the Sporting v Rangers tie in the next round.
1902: In other Scottish football news, BBC Scotland's Chris McLaughlin has discovered that the Scottish Premier League and the Scottish Football could potentially merge from next season. Celtic boss Neil Lennon, meanwhile, has come out in favour of a new 10-team top-flight. Lennon was among a number of managers at Hampden this afternoon for further talks on reconstruction.
Jim in Perth by text on 80295: "Perhaps Rangers should bring on Weiss on for the second half just to stretch Sporting Lisbon a bit?"
From Big Kev by text on 80295: "Same old Gers one up then sit back!"
"They looked comfortable, but the goal was really poor and, for the last five or six minutes, Sporting were finding spaces between the Rangers central defenders and they have to sort that out. They at least are one step better off as they have the goal and don't have to open up." BBC Radio Scotland pundit Billy Dodds
1849: There seemed to be a bit of an altercation as the players left the field for half-time. BBC Radio Scotland reporter Chick Young explains: "El Hadji Diouf went face to face with one of the Sporting defenders. He didn't quite stick the head on him, but it was seen by one of the assistants. The red mist came down and fortunately Rangers coach Kenny McDowall got between them."
1847: HALF-TIME Sporting 1-1 Rangers
1845: The sides are now locked at 2-2 on aggregate with each side having score an away goal. Should the score remain the same at the end of regulation time, extra time will ensue but another goal for either side will mean there will definitely not be extra time.
"There was a bit of confusion in the Rangers defence. David Weir looked like he was going to head it but left it and Bartley didn't have time to react and, when the ball came to Mendes, he finished superbly." BBC Radio Scotland pundit Gordon Smith
Pedro Mendes scores against his former club after running on to a loose ball on the edge of the Rangers box and sweeping a well-struck shot into the net. It's game on.
1843: GOAL Sporting 1-1 Rangers (Mendes)
1839: Joao Pereira goes down in the Rangers box under the challenge of Kyle Bartley but referee Paolo Tagliavento is not interested in any penalty claims and Steven Whittaker relieves the pressure on the visiting defence with a risky yet skilful turn on the edge of his own box.
1838: The pattern of the game appears now to be Sporting enjoying the bulk of the possession and territory and Rangers soaking up pressure and looking to hit on the break.
1835: Helder Postiga escapes Sasa Papac with a lovely chip over the Rangers defender but the Sporting strikers's shot is well over the top.
1832: Pedro Mendes tries his luck with a long-range strike but the effort flies wide of the Rangers goal. The former Ibrox midfielder will be desperate to haunt his old club.
1831: Remember you can add your comments to the live text on Twitter via the hashtag #bbcsportsound (not all contributions can be used).
"Before the goal, Rangers started to retain more possession and it paid off with the goal. We were wondering how well Sporting would cope with high balls after the first leg and that was a very good header by Diouf." BBC Radio Scotland pundit Gordon Smith
1824: Rangers now lead 1-0 on the night and 2-1 on aggregate. Can they hold on or even build on it or will Sporting hit back?
Rangers get the away goal they were looking for. Ricky Foster releases Steven Davis down the right and the midfielder's cross is headed down into the ground and past goalkeeper Rui Patricio by El Hadji Diouf. It is the Senegalese forward's first goal for Rangers.
1821: GOAL Sporting 0-1 Rangers (Diouf)
1813: El Hadji Diouf has Rangers' first effort at goal but the forward's shot from way out trundles well wide. The on-loan Blackburn player looked quite isolated when he picked up the ball.
1811: Sporting's Alberto Zapater picks up the game's first booking for a late challenge on Steven Whittaker.
"Rangers started well, but Sporting are now the ones exerting pressure. Rangers are not quite keeping possession and that has been their problem in recent weeks." BBC Radio Scotland pundit Gordon Smith
1807: Sporting look hungry for an early opener. Rangers are on the back foot.
1806: An error by Steven Whittaker allows Yannick Djalo a run and shot at goal but Rangers keeper Allan McGregor ushers the ball out for a corner.
"We keep seeing Madjid Bougherra holding his shoulder again and he has already made a couple of errors. He needs to sharpen his game." BBC Radio Scotland pundit Gordon Smith
1803: Rangers have about 3,000 fans in the stadium.
1802: Predictions are that there are less than 15,000 in a stadium that holds 50,000.
1801: Rangers get the game started with kick-off.
1758: Rangers are playing in their red and white stripped change strip while Sporting wear their traditional green and white hoops.
1755: Sporting's captain Daniel Carrico is suspended and his place in the team is taken by MarcoTorsiglieri and striker Matias Fernandez, who scored as a substitute in the first leg, earns a starting place ahead of Maniche. Abel replaces Cristiano Oliveira at right-back.
"We have decided to go with our European line-up, with three central defenders, and we hope that El Hadji Diouf can hold the ball up for us. He takes the ball into feet very, very well, but safe to say I think we will be seeing Lafferty at some stage of the game. Without doubt, we have to score if we want to progress, but you don't have to score it in the first 15-20 minutes" Rangers assistant manager Ally McCoist
1734: Should Rangers fail to progress past Sporting, this will be Smith's last European tie as Rangers manager but if the visitors turn it around and qualify for the last 16, they will face either PSV Eindhoven or Lille who are locked at 2-2 going into their second leg in Eindhoven this evening.
