Rajon Rondo questionable for Thursday's game against the Nets

Rajon Rondo left the Boston Celtics-Utah Jazz game tonight in the 3rd quarter after spraining his ankle, and according to RotoWorld, he is questionable for Thursday's came in Brooklyn against the Nets:

Rajon Rondo had six points, three rebounds and 10 assists before leaving Wednesday's game with a sprained right ankle. 
He didn't return and will be questionable for Thursday's game against the Nets. Watch the Rotoworld News Page for updates on his status between now and then. If he's out, Leandro Barbosa or Jason Terry would likely start at point guard, although Terry was buried on the bench while Rondo was out.

This is what most Celtics fans were worried about when we didn't sign a back-up point guard. It's just coming a bit earlier in the season than we would have liked. Hopefully Rondo will be OK, but if he can't play Thursday, we will get a better chance to see how Jason Terry and Leandro Barbosa do with handling the ball. Paul Pierce might also have to step in and play a little point forward.
