Josh Coulson's equaliser in the second minute of added time earned Cambridge United a 2-2 draw and replay in an absorbing FA Cup first round tie against Wrexham.
It was the centre-back's second goal of the game and it was also the second time he had pegged the visitors back after Red Dragons player-manager Andy Morrell had twice put his side ahead.
Wrexham went ahead with the game's first chance after 20 minutes when Lee Fowler's cross was met by the head of Morrell.
Cambridge keeper Danny Naisbitt did well to parry his first effort but he was left powerless as Morrell thumped the rebound into the roof of the net.
Morrell then had a low effort turned around the near post by Naisbitt and Luke Berry's shot was deflected wide as the visitors went into half-time in front.
But the U's drew level eight minutes into the second half as Coulson headed in Ashley Carew's free kick.
The Red Dragons retook the lead on the hour when Danny Wright's flick sent Morrell clear and he swept the ball first time into the far corner.
Coulson brought salvation for the hosts late on as he stabbed in from close range after Ryan Charles missed Naisbitt's long kick.
