Danny Welbeck scored on 86 minutes to claim a point for Brighton after Sheffield United took the lead through Jayden Bogle on his Premier League debut.
United were reduced to 10-men on 40 minutes when John Lundstram was dismissed for Chris Wilder's men following a nasty challenge on Brighton defender Joel Veltman.
Brighton appeared to heading for a painful home loss until Welbeck, who came on as a second half sub, fired home from close range.

9. Solly March 7/10
A very reliable performer for Brighton this season and once again a strong display from left wing back. Enjoyed a good tussle with Baldock and kept trying to provide crosses and breakthrough Sheffield United
10. Neal Maupay 6/10
Looks short on confidence at the moment. Had one good chance in the first half but the Frenchman's effort lacked conviction. Replaced by Welbeck on 66 minutes
11. Aaron Connolly 6/10
Worked hard for the team and created half a chance for himself in the first half but his angled low effort was saved by Ramsdale. Missed a great headed chance on 80 minutes from AJ's cross
12. Ali Jahanbakhsh 6/10
Came on for Veltman at halftime. Offered width on the right and provided decent crosses most notably for Connolly's missed header. Hit the bar with a close range header and should have scored the winner
