11 is still Chris O'Gary's squad number. He kept it throughout last season, despite being with Notts Forest, and he is on a season long loan again, with Burton Albion.
He is still an Albion player, so I'm presuming he will still be allocated that number.
For some reason I though Connor Goldsdon might have been persuaded to switch to one of the vacant squad numbers, 3 or 12 for instance, to let Glenn have his old number 17 back.
It doesn't look that way though.
