Former Coventry City defender Jermaine Grandison has been side-lined by a hip injury, which is expected to keep him out of League One Action for six weeks.
The Shrewsbury Town player was forced off at half time of The Shrews 2-0 defeat at Swindon Town on Saturday and Grandison has seen a specialist in London and been told to rest.
Manager Graham Turner told Town's official website: "The diagnosis at the moment is he should have two weeks rest away from training and if it settles down they will inject it. But give it two weeks rest and see how it goes from there.
"The worst-case scenario is he'll need surgery which could keep him out for months rather than weeks, but we're hoping it will settle down with some rest. We've got the best people looking at him so it remains to be seen how long he's going to be out.
"It's a possibility it will be a month and then a return to training and it's then probably another two weeks at least getting him fully match fit.
"I think the best-case scenario we're looking at is probably six weeks before he's fit but it's a problem he's got to manage now and we'll see over the next few weeks. I think that will be crucial."
