Morecambe boss Sammy McIlroy will assess the fitness of defensive duo Will Haining and Chris McCready ahead of the home clash with Shrewsbury.
The pair have been suffering with hamstring problems in recent weeks and could miss out again.
Yet McIlroy will be reluctant to make changes after his side ground out a 1-0 victory at Bradford last weekend.
Defender Paul Scott missed out through injury last weekend and will also be assessed but McIlroy is in optimistic mood following last weekend's win at Valley Parade.
The Shrimps manager has heaped lavish praise on winger Mark Duffy following his impressive start to the season.
"Mark has been excellent in recent weeks and put in some really good displays," said McIlroy.
Shrewsbury will leave it as late as possible before checking on the fitness of Shane Cansdell-Sherriff and Craig Disley.
Defender Cansdell-Sherriff sustained a groin injury in training that forced him to miss Tuesday`s Johnstone`s Paint Trophy defeat at Bury while midfielder Disley picked up an ankle knock towards the end of the tie and was forced off.
Both have got a chance of making the clash but face a race against time to prove their fitness.
Boss Graham Turner is definitely boosted by the return to full fitness of midfield pair Sean McAllister (hamstring) and Benjamin Van den Broek, the latter of whom has not featured for almost a month since suffering ankle ligament damage.
Turner made five changes for the shoot-out defeat at Gigg Lane but he will revert to his strongest XI at the Globe Arena as Shrews look to end their four-match winless run.
