The Rovers boss is hopeful that he'll have a host of players back in the squad for the match against Ian Holloway's Millwall.
Grant Hanley, an unused substitute on Tuesday night at Watford, has had a couple more days training under his belt, whilst Tom Cairney and Jason Lowe could be back if they come through training unscathed.
Rovers could also include Josh King after the Norwegian missed the midweek draw due to a back spasm.
"It is a nice dilemma to be in," said Bowyer. "The competition is good for everybody.
"It is good for the players and it is certainly good for the staff. Even if it means that it gives us a few more grey hairs thinking about who to pick and who not to pick.
"We've wanted this competition all season and unfortunately due to various injuries we've not been able to have that.
"Now we are getting it right at the run-in which could be crucial."
