The right-back, on loan from Swindon, is expected to be sidelined for at least a month having dislocated the joint early in the second half.
"We're hoping for the best - he's dislocated his (left) shoulder," revealed assistant manager Terry McDermott afterwards. "It popped out and they put it back in again, so we'll have a look on Wednesday. He'll have a scan and we'll have a bit more of an idea how long he will be out for, but I think it will be a minimum of four weeks."
McDermott was pleased with the grit and determination shown by a Birmingham side who threw away a two-goal lead against Nottingham Forest at the weekend.
Chris Eagles cancelled out Leroy Lita's opener, but Marlon King netted from the penalty spot three minutes into the second half, after linesman Steven Copeland had flagged for an apparent foul by Wanderers full-back Marcos Alonso.
"We had to battle here and we did," McDermott said. "Bolton are going to be there or thereabouts at the end of the season and if we carry on with that effort there's no reason why we can't be up there as well."
