Evening AFC West notes

Oakland rookie running back Latavius Murray had minor ankle surgery Tuesday. His timetable to return is unclear.

  • San Diego gave quarterback Philip Rivers his first rest day of camp Wednesday. Safety Brandon Taylor and running back Danny Woodhead are on pace to play Saturday at Arizona for the first time this preseason.

  • Oakland defensive tackle Vance Walker will play against Chicago on Friday. Defensive tackle Pat Sims and offensive tackle Menelik Watson, who like Walker returned to work this week, won’t play in the game. Safety Tyvon Branch has been out this week with a ribs injury and he likely won’t play Friday.

  • Oakland coach Dennis Allen said Alex Barron is expected to start. Barron, for now, is Oakland’s left tackle with Jared Veldheer out for about three months with a triceps injury. Barron did not play well last week in New Orleans.

  • Free-agent offensive lineman Jason Spitz reportedly visited the Raiders this week. If signed, it’d be for depth purposes.
