The Eagles have placed former All-Pro left guard Evan Mathis on the trade block.

Mathis was a first-team All-Pro selection in 2013 and has been one of the best guards in football the past three seasons. However, Mathis wants a raise on his $5 million salary, the Eagles want him to to take less - so apparently that's enough to show him the door, if there is a taker for his services.

The Eagles have dished out contracts to Jason Peters and Jason Kelce this offseason and now Mathis wants a pay day.  The durable left guard has been a rock since joining the team in 2011, he has missed just one game in three seasons since coming over from Cincinnati, he has routinely been one of the top rated guards in football according to Pro Football Focus and graded out as their No. 1 guard in 2012.

The Eagles re-signed Mathis to a five-year, $25 million contract back in May of 2012, a deal that included $7 million guaranteed. Mathis is 32, so he has a little wear on his tires and maybe the Eagles feel someone is ready to step in now and play left guard.
