Nerdy Football Analysis: Gates played 69 of 92 snaps last week and was in the Week 6 loss to the Packers until the end, so the Chargers are more than likely just playing it safe and giving him some rest. Allen is a bit more of a concern because he sat out the fourth quarter and overtime. Friday will be key for both players, but Allen’s owners have more to worry about here than Gates’. Steve Johnson might return from a two-week absence, although it is possibly Rivers’ top receivers versus Oakland could be Malcom Floyd and Dontrelle Inman.
