The Raiders will be without the backup services of Matt Schaub on Sunday.
The 33-year-old quarterback is out for Oakland's Week 3 contest against the New England Patriots for a non-injury related reason. He was a late add to the team's injury report. Schaub traveled to Boston with the team but had an emergency come up, per Vic Tafur of the San Francisco Chronicle.
Besides starting signal-caller Derek Carr, Matt McGloin is the only other QB on the Raiders' roster.
