The big defender is available again after missing the defeat against Liverpool through suspension but has been troubled by a back injury for the last couple of weeks.
The blow is cushioned somewhat by the return of Chris Perry after two months out with a slipped disc in his neck. He completed 90 minutes for the reserves at Leicester City on Wednesday.
Robbie Keane may also return at Bolton and Darren Anderton is available after serving a one-match ban.
"Our problems are with injuries and we've got to overcome that and try and get the likes of Dean Richards and Robbie Keane back," reported Glenn.
"Obviously Darren is back from suspension but Deano's had a bad back since he's been out."
Dean Richards is a doubt for Monday's clash against Bolton Wanderers.
