Well Vick is listed as questionable for this week's game and the Falcons really won't know until Wednesday if he'll play. I'm sure for strategic reaosns they'll be really iffy on his playing status up until Sunday. Schaub is likely get most if not all the reps in practice between now and then.
I honestly believe he will play. There might be a short leash on him, but if he's not limping, it's not a major hamstring injury IMO. According to reports, he wasn't limping today, so I think he can play. Knowing Vick, he'll want to play.
