The Facts: Greene had arthroscopic knee surgery on Monday, according to sources familiar with the situation, and could be sidelined for a week or so.

Diehards Line: Greene, who signed with the Titans this offseason after four seasons with the Jets, rushed for 18 yards on four carries in the opener against the Steelers, but he injured his knee in that game and hasn’t practiced since. Greene did not play on Sunday against the Texans, as Jackie Battle worked behind Chris Johnson at running back. Battle will face his old team – the Chargers – on Sunday at LP Field.
