The Jets added Reggie Hodges to the injury report with what they call a thigh injury. He is listed as "questionable" - the Jets favorite category to use.
The Jets never reference hamstrings, but the guess here is this is a pulled hamstring.
If Hodges can't go, the Jets could elevate punter Waylon Prather from the practice squad.
The Chargers added running back Darren Sproles to their injury report as probable with a hamstring injury. They list hamstring injuries by name, unlike the Jets.
