Graham Turner has called on the whole Shrewsbury Town squad to come together to support the club's promotion push.
Starting at Torquay on Saturday, Town face eight League Two games in 29 days.
"Team selection can change quickly, through loss of form, freshening things up, or for whatever reason," Turner told BBC Radio Shropshire.
"I've stressed to players like Nicky Wroe, Sean McAllister, Lionel Ainsworth - players looking to get back into the side - to keep grafting."
He continued: "Marvin Morgan is suspended, and we've also got Shane Cansdell-Sherriff and Reuben Hazell coming back from injury.
"We've got a good squad with good players, and they've all got to be ready to step in at a moment's notice."
