Torquay are sweating on the fitness of striker Rene Howe.
Howe picked up a suspected groin injury in training on Thursday and is rated doubtful by the club ahead of the visit of the Shrews.
Taiwo Atieno would be the obvious replacement up front for manager Martin Ling should Howe not be fit enough to take part.
Otherwise, the Gulls boss has no new injury or suspension worries as he looks to lead his side to their sixth straight league victory.
Defender Angus MacDonald signed on loan from Reading until the end of the season during the week and could be set to make his debut, although the 19-year-old will have to force his way past one of Brian Saah and Mark Ellis to claim a spot in the heart of defence.
Meawhile, Shrewsbury are hopeful Matt Richards will be fit.
The midfielder has picked up a minor calf strain this week but should recover in time to be in contention at Plainmoor.
Otherwise, manager Graham Turner is not expected to have any new injury or suspension problems as his side once again aim for a fourth successive victory following the postponement of last weekend’s clash against Port Vale.
Striker Marvin Morgan continues to miss out due to his red card against Southend, with the Gulls clash the second game of his three-match ban.
Defenders Shane Cansdell-Sherriff (shoulder), Reuben Hazell (knee) and Connor Goldson (back) all continue to make good progress with their respective recoveries but are not yet ready.
