SAN DIEGO -- San Diego Chargers running back Ryan Mathews has a sprained medial collateral ligament in his right knee and will be out for an undetermined amount of time. Mathews was taken off the field on a cart Sunday after hurting his knee trying to recover his own fumble in the fourth quarter of a 30-21 victory against the Seattle Seahawks. The Chargers didnt say to what degree the ligament was injured, which would help narrow down how long Mathews is expected to be out. "In all fairness to him and the training staff, everyone recovers differently," coach Mike McCoy said Monday. "Im not a doctor by any means so I cant look at an X-ray or a picture and say, Oh its going to be this long. Weve had players who were supposed to be done for the season and the next thing you know they come out there Monday or Wednesday and theyre practicing with something torn or something broken or this or that. I dont want to put a timetable on anything. Its unfortunate but its part of the game." Mathews, who is in the fifth and final year of his contract, was injury-prone in his first three seasons. Last year was the first time he played all 16 regular-season games, rushing for a career-high 1,255 yards. He did sprain an ankle late in the season but played through it until finally being forced to the sideline during the Chargers divisional-round playoff loss at Denver. Mathews also has had trouble holding onto the ball during his pro career. The Chargers (1-1) have Danny Woodhead, Donald Brown and rookie Branden Oliver at running back. This was the kind of situation the Chargers envisioned when they signed Brown in the off-season as an unrestricted free agent from the Colts, who drafted him in the first round in 2009. McCoy said he expects Brown to step in just as Rich Ohrnberger stepped in at centre after Nick Hardwick was lost for the season following the opener due to a recurring neck stinger. "Donalds played a ton of football," McCoy said. "The number of snaps he got in Indy in a very similar system, when he was with Peyton (Manning), so coming here we knew exactly what he can do. Weve got a lot of confidence in him. Weve said that were going to play all our backs, certain rotations, certain number of plays. Some weeks its going to be more than others and its the second week in and theyll take a few more snaps. We have confidence in all our players. Thats why theyre here." The Chargers say nothing changes in the wake of their big victory over the defending Super Bowl champions. Tight end Antonio Gates caught three touchdown passes from Philip Rivers and the offence controlled the tempo to help keep Russell Wilson and Marshawn Lynch off the field. Up next is a trip to Buffalo, which leads the AFC East. "Victory loves preparation," Ohrnberger said. "Its a motto we have in the offensive line room. Its something thats important to us. Regardless of the opponent, were going to respect them just the same. The defending world champs came in here yesterday, and were going to prepare for the Buffalo Bills, who are 2-0, just the same way we did for Seattle. Thats just it. Its all in the preparation. Youve got to give all these teams respect." Stephen Strasburg Nationals Jersey .
