Striker Keogh has been playing recently despite a broken toe but was forced to withdraw from the warm-up at Brighton on Tuesday night.
However, the Lions are confident the extra rest means he will be able to play on Saturday.
Winger Taylor came off with a knee knock early in the second half of the 2-2 draw on the south coast and he will be assessed.
Forward Darius Henderson was on the bench at Brighton after a hamstring injury and should be involved again.
Therefore skipper Paul Robinson is the only definite absentee with the defender continuing his recovery from a pelvic problem.
