Swindon snatched a 1-1 draw at promotion rivals Cambridge courtesy of Joel McGregor’s goal in the 90th minute.
The Robins had been second best throughout and trailed through Ben Knight’s effort, only for McGregor to be fed by fellow substitute Billy Bodin and fire a precise first-time finish into the far corner.
The hosts had dominated the chances prior to that, with Adam Mayor firing into the side-netting early on.
Cambridge got a deserved opener after 21 minutes when Mayor found James Gibbons, whose centre was swept home by Knight.
Knight was found in an almost identical position by a Louis Appere delivery, but this time he could only fire well over.
He then turned provider for James Brophy, whose low shot was kept out by a sprawling Conor Ripley save.
Knight should have made it 2-0 nine minutes after half-time as he surged past multiple challenges before being denied by Ripley.
Mamadou Jobe stabbed a Brophy corner over before the hosts were made to pay for their missed chances at the death.
