Leeds United defender Liam Cooper has not played since the start of December.
Leeds captain Cooper has been out since the start of December, and underwent knee surgery to correct the problem last month.
The centre-back is now edging closer to fitness, in what is a boost for Leeds.
But Bielsa will not throw him straight back into Leeds’ line-up, as he likes returning players to get their match sharpness back by playing for the development side.
Leeds are now set to take on Queens Park Rangers in the FA Cup this weekend, and it is Luke Ayling who will get the nod to play in the heart of defence.
“Ayling needs to play because he feels he has not reached 100% of his performance,” Bielsa said. “With [Kalvin] Phillips suspended and Liam Cooper will play with the U23 before the Championship.”
Cooper’s return will be a boost to Leeds, as they have struggled badly with injury this term.
The Whites have suffered fitness problems with a number of their key players, but they have still managed to perform brilliantly.
Leeds lead the way in the Championship, although they have suffered back-to-back defeats most recently and will be keen to get back to winning ways at Loftus Road on Sunday.
