It's been a rough season for San Diego Chargers running back Ryan Mathews. He suffered his biggest disappointment Sunday, especially for fantasy owners who've stuck with him.
Mathews suffered a broken left clavicle during the first half of a 31-7 loss to the Carolina Panthers and is out for the season, according to U-T San Diego. Mathews has struggled to show he can be consistently effective or durable.
There likely will be a new head coach and a new general manager in San Diego next season. They probably won't have faith that Mathews can be a "foundation" starting running back.
Here are the other injuries from Week 15:
- The Baltimore Ravens might have the most injury problems in the NFL, with their defense in especially terrible shape. Now their offense has issues, too.
Wide receiver Torrey Smith suffered a concussion during Sunday's 34-17 loss to the Denver Broncos. So did backup running back Bernard Pierce. Linebacker Terrell Suggs battled through a biceps injury and clearly wasn't fully healthy. The Ravens suddenly have to worry about getting healthy enough just to win the AFC North.
- Minnesota Vikings defensive end Brian Robison left with a shoulder injury early in a 36-22 win over the St. Louis Rams and never returned.
- The Chicago Bears' rotating offensive line took another hit in a 21-13 loss to the Green Bay Packers: Right tackle Jonathan Scott was forced out in the second quarter with a hamstring injury.
- Washington Redskins right tackle Tyler Polumbus suffered a concussion during a 38-21 win over the Cleveland Browns.
- The Miami Dolphins lost three players to injury during a 24-3 win over the Jacksonville Jaguars: fullback Charles Clay (knee), safety Chris Clemons (stinger) and cornerback Nolan Carroll (knee).
