Leeds United take on Fulham on Wednesday night, in what will be Steve Evans' first game as manager.
Cooper looked in agony during Leeds' match against Birmingham City at the weekend, as he hobbled off the pitch with a knee complaint.
However, the centre-back has made a quick recovery, and Evans has confirmed that he will be part of the squad which goes to Craven Cottage in midweek.
"I'll give you a surprise, Liam Cooper will be on the team coach for Fulham," Evans revealed. "He trained this morning. I have seen the pictures on television on Saturday evening, and you see the boy come off like that [and you worry].
"But I've had a good chat with him and he's done a good fitness session with the medical team, who have seen fit to say he's good enough to go on the coach. If he's not involved at Fulham, he'll certainly be involved against Bolton. That's great news."
Cooper's return to Leeds' team will be a major boost, as he has been one of their more reliable performers in the centre-back role throughout the season so far.
It wasn't all good news on the injury front for the Whites, though, as Evans suggested that Taylor could still be out for at least another fortnight.
The left-back missed Leeds' match against Birmingham, and he is still undergoing scans to assess the severity of his problem.
"Charlie's just about a period of time," Evans added. "We're talking two or three weeks. He has to have a scan and make sure there's no potential damage going towards the spleen."
Leeds go into their game against Fulham on Wednesday sitting in 18th place in the Championship, and having lost their last three games.
