Chargers running back Ryan Mathews practiced Friday, taking part for the first time since he suffered a sprained MCL in his knee in a Week 2 win over the Seattle Seahawks. Ryan Mathews has not played for the Chargers since spraining the MCL in his knee Week 2. "Being able to run again is encouraging," Mathews told the Associated Press. "That's a big step. I'm very encouraged. The trainers are doing a great job and I'm just following their plan. Every time they put me through something I'm just trying to do my best." http://espn.go.com/nfl/story/_/id/1...iego-chargers-practices-first-mcl-knee-sprain
