San Diego Chargers starting running back Ryan Mathews will undergo surgery Friday morning for a broken collarbone.
Mathews was injured on his first carry of the preseason in the first quarter of Thursday night's game against the Green Bay Packers. Coach Norv Turner has said he'll be out four to six weeks.
A four to six week timetable has Mathews returning within the first few weeks of the season. The Chargers have a wealth of unspectacular options behind Ryan Mathews in Ronnie Brown, Curtis Brinkley, Jackie Battle and LeRon McClain. We doubt any one back will take on a featured role as was the plan for Mathews. First round running back options are getting thinner by the day.
