The striker has expressed his disappointment via his personal website that a recent bid by Wolves to take him on loan was rejected.
But the boss reasoned that he turned down the loan request with our busy Christmas and New Year period in mind - five games, including the FA Cup, in 12 days.
Glenn said: "I sat Les down and explained the position, that he could move, once the transfer window re-opens, if we received an acceptable bid.
"Unfortunately he's been out for three weeks with a hamstring injury."
Glenn Hoddle has confirmed that Les Ferdinand will be allowed to move once the transfer window re-opens in January.
