The former England Under 21 international, who scored twice for the reserves in midweek, is unlikely to start the game because of the fine form that Martin Butler and Jamie Cureton find themselves in.
Fozzy, last season's top scorer, admitted: "I will have to make do with a place on the bench as the whole team played well against Coventry.
"Even though we lost we played very well, we were on top until they scored. I thought we were thye better side. Butler and Cureton up front did very well so I'll have to sit it out and wait.
"I felt alright after the reserve game on Tuesday. It was a hot day so maybe the pace wasn't as fast as it should have been but it was nice to score two goals."
Leicester, one of the promotion favourites, last weekend lost 6-1 at Ipswich and will want to avoid another defeat tomorrow.
Forster added: "It will be an interesting game because although Leicester lost heavily we lost as well so both sides will be desperate for the points.
"When teams take a big defeat like that they just go back to the basics and work extra hard - if we want to get anything out of the game we'll have to do the same ourselves."
