On Monday, Chargers HC Norv Turner addressed how the team planned to move forward without RB Ryan Mathews.
“Well, we’ve got a chance to get Ronnie Brown back” he said. “[Jackie Battle] will get a chance to play. And [Curtis Brinkley] played some yesterday, though I don’t know that he would play on third down. And we’ll probably add Edwin Baker to the 53-man roster. I don’t know that he would be active, but we’d have to see where Ronnie Brown is.”
Reading the tea leaves, it appears that the RB depth chart goes Brown, Battle, Brinkley and Baker, but it's a crapshoot. Battle and Brown figure to split the work if Brown can play, but Brinkley did get more touches than Battle in Week 15.
