Ryan Mathews moving closer to field

You have to love Ryan Mathews’ attitude.

The truth is, though, his fight is against the calendar, not his own expectations.

U-T San Diego reported that the San Diego Chargers’ running back received good news Monday as he recovers from a broken clavicle he suffered on his first carry of the preseason on Aug. 9. He has been cleared to do upper body exercises in addition to the lower body work he has been doing all along.

When he was injured, the team said his recovery timetable was about 4-6 weeks. ESPN medical analyst Stephania Bell told me she thought Mathews’ injury could be closer to the six-week range.

However, Mathews has been steadfast in his optimism. He has said all along he expects to play at Oakland on Sept. 10 on ESPN’s “Monday Night Football.”

The key will be if Mathews can practice next week. He will need to shake off the rust in addition to making continued strides in his upper body. The good news is, Mathews shouldn’t miss much of the season.
