The midfield man has been missing since the win over West Brom in early December, having made a huge impression in the opening stages of the season.
"Jamie has done a bit of jogging," reported Glenn. "He is off the crutches and his rehab has truly started now - so that is good news for us.
"Starting jogging is sort of the first port of call for him after throwing away the crutches. Good news.
"I can't give you too much other injury news because there isn't that much."
Jamie Redknapp stepped up his rehabilitation on Monday by jogging for the first time since sustaining a stress fracture of the toe.
