Leeds United boss Neil Redfearn has confirmed that Rodolph Austin will be sidelined for up to three weeks with a thigh strain.
The midfielder suffered the problem during Saturday's 3-2 defeat to Watford in the Championship.
Austin, who has scored three goals in 27 games this season, is expected to be back in action before the end of the month.
Leeds continue their Championship campaign on Wednesday when they entertain promotion-chasing Ipswich Town.
