NFL.com's Dan Hanzus reported that Schaub's injury does not appear to be serious and that he'll be evaluated on a day-to-day basis. It could explain some of Schaub's struggles this preseason. The 33-year-old Schaub completed less than 50 percent of his passes against the Green Bay Packers on Friday night for just 110 yards. He has had trouble moving the Raiders' offense.
Coincidentally, the storyline bears a resemblance to the Raiders' quarterback struggles heading into last season. Matt Flynn, who is no longer with the team, entered last preseason as the favorite to win the starting job. But he was plagued by elbow problems and eventually lost the competition to Terrelle Pryor.
According to Hanzus, rookie quarterback Derek Carr earned first-team reps in Sunday's practice.
