While he still has a looong way to go before he's recovered, technically, his bone break should have healed.
In the article he wrote he said that he "tore ligaments" and they had to be surgically repaired. I'm not sure about the length of time it takes for that to heal, but he should be able to start getting out of his boot and doing some stretching/light walking exercises soon I would imagine.
I'm sure it's seemed interminable for Gordon, but it does seem to have gone by quickly. And you can be sure that the whispers about "will Gordon return this season" will begin in earnest come the first of the year.
