Cole told TalkSport: "I don't want to put a date on it. I played a reserves game last Friday and I come through 60 minutes behind closed doors.
"I will be training again this week. It's been a long time (out with the injury) so I don't want to say when or where, I'm just at the tail end of the rehab. I'm back training with the first team and the reserves so whenever I'm fit."
