The midfielder has joined on a loan spell until January.
It looked as though the deal was dead and buried but the late intervention of Steve Evans saw the Yorkshire club get their man at the last minute.
Bridcutt was signed by his former boss at Brighton and Hove Albion Gus Poyet at Sunderland but has struggled to feature regularly for the club since the Uruguayan departed.
Now the defensive midfielder is at Leeds, with an option to extend his loan deal in January.
Something he is clearly open to. He is quoted by the Sunderland Echo as stating:
“I’m not too sure. I’ve not had a lot to do with Sam. Obviously he didn’t come in long ago himself.
“He’s got his own ideas of what he wants to do.
“At the minute, I’m not part of that.
“But I’m here at Leeds now until January.
“If all goes well and I get the games, and the manager is happy with me, then I’m happy to stay.”
It certainly seems as though Sam Allardyce simply does not rate the midfielder highly enough for what is looking like a relegation scrap this season at the Stadium of Light.
But there loss could be Leeds' gain. Bridcutt was an excellent performer for Brighton in the Football League and the promise of him potentially staying for the entire season must excite fans.
Hopefully he can have a bigger impact than his Sunderland team-mate Will Buckley, who was sent back to Wearside yesterday after a fruitless loan stint.
