Tranmere boss Les Parry is facing an injury crisis ahead of Saturday`s trip to Yeovil.
Seven senior players missed last weekend`s 1-0 home win over Peterborough and Rovers` casualty list has worsened this week.
Ian Goodison, Adam McGurk, Sam Morrow and Enoch Showunmi are all nursing injuries and could miss the match at Huish Park.
Parry said: "We are not going to get back any of the players who were out last week and we could lose some more.
"I brought in the FA coach, Neil Bailey, this week to do some work with the players. It's something I started doing last season, bringing in guest coaches in to make the sessions different. But we had only 12 outfield players for him to work with."
