Just as one member of the Eagles offensive line is ready to make his return, another member of the line will miss the rest of the season.

Eagles starting left guard Evan Mathis is expected to be activated from short-term I.R. in time for Week 10 against the Panthers. Mathis has been out since the first week of the season with a sprained MCL.  Meanwhile, Eagles starting right guard Todd Herremans will undergo season-ending surgery, and be placed on injured reserve due to a torn right biceps.

Herremans attempted to play through the injury in Week 9, but was ineffective, and ended up suffering an ankle injury in the process.

With Mathis returning, taking Herremans place with be Matt Tobin, who will move from left guard, where he has been starting in place of Mathis, to right guard.

The Eagles starting offensive line from one year ago will not have played one full game together the entire season.  With Herremans’ season-ending injury the Eagles starting offensive line will look like this: Jason Peters, Mathis, Jason Kelce, Tobin, and Lane Johnson.

Thos could be the last we see of Herremans in Philadelphia, now 32, he's signed through 2016, but has no guaranteed money remaining on his contract. His $4 million salary for 2015 makes him a candidate for release - consider Tobin to be the future and if he plays well enough he could be the starting right guard in 2015.
