A controversial last-minute Simon Cox penalty saw 10-man Swindon salvage a draw with league leaders Swansea City.
The Robins, looking to extend a three match unbeaten run, saw Barry Corr red carded after 20 minutes for violent conduct after tangling with Garry Monk.
After a long rearguard action, Thomas Butler put Swansea in front in the 87th minute, rifling in from 16 yards.
Kris O'Leary fouled Cox to concede a penalty in a frantic finale, and the striker coolly slotted the spot-kick.
It was the first time the Swans had failed to find victory in seven games, but Roberto Martinez's team stay top of the league.
