The 27 year old has been sidelined from the start of December and he is back in training after recovering from his knock. The defender is back out on the training pitch at Thorpe Arch.
Cooper underwent surgery in Italy earlier this month and he seems to have returned earlier than expected.
Marcelo Bielsa will be delighted to have a key player back for the intense festive period and the fans were quite happy with the news as well.
Cooper has been outstanding for Leeds this season and he will make a big difference to their title challenge during the second half of the season.
