Kalvin Phillips and Rodrigo could feature for Leeds Under 23s on Friday in a bid to prove their fitness in time for Monday's Premier League game at West Ham.
Midfielder Phillips has missed Leeds' last four matches with a calf issue and forward Rodrigo has been sidelined since the end of January due to a groin injury.
'Some players coming back from injuries will play in the (U23s') game tomorrow (against Wolves),' Bielsa said.
Winger Ian Poveda (ankle) and midfielder Jamie Shackleton (groin) are also nursing injuries and Bielsa did not clarify which of his injured players were closest to a return to contention.
