Connor Wickham had a successful spell at Yorkshire rivals Sheffield Wednesday earlier on this season, netting eight goals in 12 appearances.
The highly-rated striker was signed by the Black Cats in 2011 in an £8.1million deal, which could potentially rise to £12million, from Ipswich Town. However he has struggled to secure a permanent role at Sunderland. Wickham has played under four different managers during his three-year spell at the club, which has often seen him sent out on loan.
Wickham spoke of his joy regarding the move in an interview with the club's website:
“Once I heard Leeds were interested in signing me there were no other choices and no doubt I wanted to come," he said.
"I played against Leeds earlier this season with Sheffield Wednesday. The potential here is a big. There are some players here that I know already, and the team is looking to push towards the Play-Offs. Hopefully I can help with that. I just want to play football and do the best I can, and hopefully push the team into the promotion picture.”
Leeds manager, Brian McDermott told the club website, "We are delighted to have signed Connor until the end of the season.
"There was a lot of competition for his signature, but he was very keen to come and play at Leeds United. He is another young English player who has everything in front of him."
Leeds' main competition for the striker came from Sheffield Wednesday and Owls fans will be sad to see the striker didn't chose a move back to Hillsborough, after his successful stint earlier on in the campaign.
Wickham incidentally helped put Leeds to the sword earlier on this season, with one goal in Wednesday's 6-0 victory over McDermott's team.
Can Wickham fire Leeds into play-off contention?
