Lavia made his latest comeback in a Blues shirt in last week's defeat at home to Brighton.
"Romeo is ready to play," said Maresca during his pre-match press conference. "With Romeo we are trying to do exactly the same as we have done with Wes (Fofana) and with Reece (James).
"We are now in a much better position with both of them. Unfortunately, at this moment, Wes is out but not for any physical problem, just the concussion against Lincoln City.
"The target for Romeo is to help him and bring him to the same condition as Wes and Reece, where they can play games.
"You can see now Reece is playing more games without problems. Hopefully, we can do the same with Romeo."
