Schaub was not at team headquarters on Friday because of a "personal issue that he's dealing with," the head coach added.
Allen recently insisted there are no concerns with Schaub's elbow.
Allen has bungled this process from the beginning, however. Can Raiders fans trust him to make the right decision if he denies seeing a lack of arm strength from a quarterback who can no longer throw convincingly beyond 10 yards?
If football acumen trumps financial commitment, Allen will go with a younger quarterback capable of making plays beyond the line of scrimmage. In which case, it's entirely possible that Schaub will never take a regular-season snap for the Raiders.
