Assuming no setbacks, I still think his return will be March 4.
He has stated his goal is to come back around his birthday (March 3) and also in a home game, and the C's play the Hornets on March 4 at home, and there's another game March 6 at home. Good time to make a return and at least get his feet wet. Obviously he will be on limited minutes and not playing any B2Bs, but he can still ramp up for beyond April hopefully.
I know he's said or mentioned February as well, but I would still play it a little safe.
