Spiller (ankle) is considered week-to-week, Lindsey Thiry of ESPN.com reports.
He won't play in the Chargers' final preseason game and can be considered questionable for Week 1 against the Raiders. Even if he gets healthy, it isn't clear Spiller will have a role in the season opener, as he ran behind Joshua Kelley and Larry Rountree this preseason. The rookie fourth-round pick is capable of moving ahead of those players as the year progresses, but this ankle injury probably ends any chance Spiller will do it before Week 1.
