I would imagine that with his suspensions he is already close to being on the bubble but him staying on the team now... is based on his play versus his competition. One preseason game is to early to tell.
I think there is to much time left in TC not to mention watching him in preseason when it counts to make any decisions on if he will be on the 53 man roster. I will say I hope he plays well at game time given his speed. In the words of Gman you cannot teach speed. Given his speed he could make a difference if he can master his trade.
