Sunderland boss Martin O'Neill admits Wes Brown won't play again this season.
O'Neill confirmed Brown has been back in training but is unlikely to feature in any of his side's remaining fixtures.
"He's joined in training on a few days and then has to take some time out again," O'Neill said.
"At the moment, however, I think he's reversing that trend - it's one little step at a time at the moment."
