Raiders' Darius Philon: Suffers significant injury

Philon suffered a significant knee injury Sunday against the Chargers, according to head coach Rich Bisaccia, Josh Dubow of the Associated Press reports.

Philon's exact injury is unknown as is a timetable for a return. However, it doesn't sound good regarding Philon's ability to come back at any point in the playoffs if the Raiders are able to advance past the Bengals on Saturday.
