Briscoe is one year in to a five-year deal with Hull
Tom Briscoe produced a stunning 80th-minute tackle to earn Hull a dramatic win over local rivals Hull KR.
After Danny Houghton and Josh Charnley traded early tries, the boot of Danny Tickle gave Hull a 10-6 half-time lead.
Clint Newton levelled things up before Willie Manu and Shaun Berrigan crossed to take the hosts 10 points clear.
Liam Watts' 72nd-minute try set up a tense finale and Rovers thought they had equalised through Peter Fox, but Briscoe had pushed him into touch.
Briscoe's gallant effort ensured that Hull backed up their 18-14 win at Craven Park earlier in the season, ended Rovers' four-match unbeaten run and moved three points clear of Leeds in fourth place.
The home side took the lead when Sam Latus dropped a high kick, allowing Danny Westbrook to play in Houghton.
Tickle took Hull further ahead but, after Mark Calderwood dropped the ball on the line when presented with the chance to extend the hosts' advantage, Rovers got on the board when Charnley crossed after good work by Newton.
Hull had further chances before the break in the shape of Kirk Yeaman and Epalahame Lauaki but could only add another Tickle penalty and were made to pay for their profligacy after the restart when Newton ran on to a Michael Dobson pass to score his fifth try in as many games.
But from level-pegging, Hull looked to have built an unassailable lead when Yeaman batted back Richard Horne's kick to allow Manu to cross and Berrigan touched down after superb work by Calderwood to keep the ball in play with his right boot.
A 26-man brawl which resulted in Calderwood and Ben Cockayne being sin-binned preceded Watts' score, but any hopes Rovers had of snatching at least a point were dashed by Briscoe's late heroics.
Hull FC coach Richard Agar said:
"Our boys were stung by the performance last week. When I look down our roster I still see a good side.
"Our home form has been good and we've bounced back from defeats well.
"There was plenty of drama at the end. We only needed to take one of the three or four clear-cut chances that we didn't to put the game away."
Hull KR coach Justin Morgan said:
"I've got no complaints. I thought they played very well in the first half.
"They won the field position and made it difficult for us to come out of our own end. We did well to be in the game.
"With the high standards we've set, we didn't hit too many of those markers today. We did well to find ourselves in the 79th minute and in the game."
