The next 24 hours are crucial for Grant Hall after he limped off during Saturday's QPR draw with Reading.
Last season, the former Tottenham centre back broke his Rs scoring duck against Royals for the same result - this time the club hopes it's no more than a thigh or calf strain and a minimal time out of action.
Tests will reveal the extent of the damage after Hall went down off the ball on 35 minutes and immediately signalled to the bench.
And with just 72 hours until Bristol City come to the capital, Hall is unlikely to be risked for Tuesday night’s game.
The one consolation for Hasselbaink is centre-back is a place where he has options with both Joel Lynch, who played left back against the Royals and Steven Caulker, the man who replaced Hall ready to step into the breach alongside skipper Nedum Onuoha.
