I wouldn't think he'd practice with the first team on his first day back, especially on a Friday. He wasn't going to be 100% and they weren't going to want to push him the whole practice, so putting him in with the first team would only have been disruptive to the rest of the offense. By Fri, they are wanting to have the final touches on the game plan worked through and have a solid practice. That's not a time to test your QB's leg. I'd say the fact that there were no incidents on Fri with him and they seemed to find what they wanted with his leg is is an indication that he's on schedule to have a chance on Sun.
