All the action from the second quarter-final at the African Cup of Nations.
Major goalflashes and incidents (all times GMT):
1802:The referee blows for full time, bringing to an end a game that will go down in Cup of Nations history for the wrong reasons. The fog never left the pitch, nor did the fractious nature of a match littered by fouls and ill tempers. Tunisia players do a lap of honour as they celebrate reaching their first semi-final since 1996. Senegal exit the tournament having failed to convince and having failed to secure a much-coveted first major trophy.
1801: At the other end, Habib Beye fires a volley just wide of the joint of crossbar and post. Bhadra is booked in arguments that follow for no apparent reason.
1800: Benachour receives the ball with no one between him and the Senegal goal, but the midfielder strikes his shot over the bar from just inside the penalty area.
1800: Slim Benachour is booked with only two minutes of the match left.
1757: Santos is replaced by Imed Mhadhebi. Santos takes time to leave the pitch, prompting remonstrations on the pitch from the Senegalese players. Diop pushes Santos off the pitch and Bouazizi takes a slap in the face during the melee. The game is in chaos.
1755: Sylva comes out out of goal, prompting Santos to shoot at goal from inside his own half. He tries to pass the ball into goal from fully sixty yards, but unsurprisingly the strike is wide of goal and comes up short.
1754: Santos fires over the bar when set free in the Senegalese area. In an apparently unrelated incident, Braham the substitute gets booked.
1753: The fourth official signals ten minutes of stoppage time.
1752: Camara flicks a header wide after Niang overhead kicks the ball into the 6-yard box following Bouba Diop's header onwards.
1752; Bhadra comes back onto the pitch.
1751: Senegal win a corner as the match goes into injury time.
1749: This time, Bhadra goes down following another challenge from Pape Bouba Diop. Tunisia coach Roger Lemerre tries to calm players from both sides down on the sidelines, with Diouf coming off the pitch to remonstrate with the Tunisian squad members.
1748: Mnari is replaced by Adel Chadli.
1747: Mnari receives treatment off the pitch after taking a knock in a challenge with Pape Bouba Diop. The Tunisian goalscorer looks to be out cold.
1746: Diomansy Kamara replaces Lamine Sakho for Senegal.
1742: Senegal win another corner as Jaidi takes no chance to head a loose ball behind. Nine Senegalese players go into the box but the ball is cleared.
1741: Senegal win a corner after Bouba Diop hits a ball behind the Tunisian defence which Jaidi clears. Bouba Diop heads Diouf's corner wide of goal from near the penalty spot.
1741: Santos is booked.
1738: Tunisian striker Jaziri is replaced by Najeh Braham.
1737: Diouf hits a free-kick from 30 yards straight into the Tunisia wall. Faye's shot is blocked, with the Senegalese claiming handball, and then Diouf seizes on the rebound but strikes so wide of goal the ball goes out for a throw but the referee awards a goalkick.
1736: Anis Ayari swings an elbow at Diouf, but fails to connect with the Senegalese player nor attract the attention of the referee.
1735: Jaziri is booked for dissent.
1734: Senegal coach Guy Stephan makes the first change of the match, as he brings on Mamadou Niang for Salif Diao.
1726: GOAL Tunisia 1-0 Senegal
The Rades stadium audibly explodes, and flares light up the stands, as, from twelve yards out, Jawhar Mnari heads home Jaziri's overhead kick following neat play down Tunisia's right flank. Lamine Diatta fails to clear the ball off the line. Members of the Senegalese squad invade the pitch to complain to the referee, perhaps because the official failed to award a free-kick to the Teranga Lions following Khaled Badra's challenge on Diouf a few seconds before the goal. The smoke from the flares mixes with the fog to make events on the pitch even harder to see.
1724: The game continues to be littered with fouls, but as yet the referee has shown only two yellow cards - both to Senegal players.
1721: Jaidi lets fly from 30 yards down the right-hand side of the pitch, but his strike fails to trouble Senegal goalkeeper Tony Sylva, who has yet to be forced into a real save by the Carthage Eagles players.
1718: Cisse strikes at goal but his shot hits the refere. Seconds earlier, Diouf had worked an opening down the right-flank with a determined run.
1717: Pape Malick Diop fires a strike inches wide of the Tunisian goal after Boumnijel punches a free-kick straight to the Senegal centre-back.
1713: The ball goes behind for another corner, from which Ayari's strike is deflected behind off Pape Bouba Diop for yet another corner. This time, the Senegalese clear the danger.
1712: Jaziri forces the first corner of the half for Tunisia.
1711: Mehdi Nafti fires over the bar from distance in Tunisia's first attack of the half.
1707: Tunisia kick off the second half. Fog continues to impair visibility in the stadium. It is hard for fans to see the stands on the other side of the pitch to them given the blanket of fog.
1649: The referee blows his whistle to end a half which has been short on goalmouth incident. The game is very tight with midfield play as dense as the thick fog that hangs over the pitch in the Rades stadium.
1648: Boumnijel spills the corner but is rescued by one of his defenders who hooks the ball clear.
1648: Senegal win a corner as they push forward at the end of the half.
1646: The fourth official signals four minutes of stoppage time at the end of the first half.
1644: Salif Diao becomes the second Senegalese player booked in as many minutes as he tugs the shorts of Tunisia's Santos as the forward looks to break clear.
1643: Pape Bouba Diop is booked by the referee for dissent.
1640: Camara breaks clear down the right-hand flank but Jaidi slides in to smother the danger. Senegal have yet to create a shooting chance from open play.
1639: The play is still very congested in midfield, with neither side yet to get behind their opponents' defence. Thick fog hangs over the stadium as two of the tournament favourites look to secure a semi-final berth.
1636: Bouazizi goes down again following a challenge from Pape Bouba Diop.
1632: Senegal win a corner as Karim Hagui heads Camara's far-post cross behind the goalline. The corner comes all the way to Camara on the far side but he mishits his strike and the ball bounces innocuously past Boumnijel's left-hand post.
1629: Play is again held up for an injury as Tunisia's Riadh Bouazizi receives treatment following a knock the midfielder took in an aerial challenge from Sakho.
1627: Jaidi brings Diouf down unfairly again, but apart from awarding the free-kick the referee takes no action against the Tunisian defender.
1625: Diouf is back on the pitch in time to see Sakho strike at goal but the forward's shot is immediately blocked.
1624: El Hadji Diouf appears to have been singled out for special treatment from the Tunisia defence, who constantly bring the two-time African Footballer of the Year every time he takes possession. He is stretchered off the pitch following this latest poor challenge by Radhi Jaidi.
1620: El Hadji Diouf swings a cross into the Tunisian box from the right-hand flank but Lamine Sakho just fails to get his head to the ball and register an attempt on goal.
1616: The game is very tight as both teams, who are keeping their shapes well, probe for an opening.
1615: Play is held up as Anis Ayari is stretchered off the pitch. Ayari appeared to injure himself while clearing a ball with an overhead kick. He is soon back on the pitch.
1611: Tunisia captain Khaled Badra fires a long-range free-kick straight into the Senegalese wall.
1608: Ibrahima Faye heads the ball over the bar from under his own post following Ayari Anis' deep cross. Tunisia's resulting corner comes to nothing.
1606: Zaid Jaziri picks up a loose ball on the edge of the box as a Tunisia free-kick is not cleared and fires at goal but Senegal centre-back Lamine Diatta heads the ball over for a corner, the first of the match. From the corner, Santos heads Jaziri's cross over.
1604: Another free-kick is swung into the Tunisia area by Henri Camara, standing on the right flank near the penalty area, yet Salif Diao fails to keep his header on target.
1601: Senegal's Pape Malick Diop heads Henri Camara's free-kick wide at the back post. Diop rose well and, though challenged, managed to steer his header just inches past the right-hand post of Tunisia goalkeeper Ali Boumnijel.
1600: Every touch the hosts make as they begin the game is cheered by the local supporters.
1600 GMT: Before a packed Rades stadium, Senegal, wearing an all-green strip, get the second quarter-final underway.
Tunisia name six changes to the team that drew with Guinea in their last Group A game.
