The defender has been out with concussion recently.
Once again Leeds United boss Steve Evans finds himself with a selection dilemma ahead of this weekend's tie with Rotherham United.
But Cooper suffered an ugly head injury against Huddersfield Town in the 3-0 win and had to leave the field. Bamba came on and excelled and there is no doubt that Evans is now being pushed to make a decision on the starting defenders this week.
Cooper is fit again but Bamba and Bellusci performed well in the game, so does the Scot come straight back into the starting line-up?
Leeds fans will remember Bamba and Bellusci partnering up with disastrous outcomes against Middlesbrough earlier in the season - but both appear to be improving as the season goes on.
Cooper has also been impressive and he offers balance to the centre-back pairing.
So Evans has a serious selection headache ahead of the Yorkshire derby against his former team Rotherham United.
