Walter Thurmond

There is not much longevity in the NFL and Thurmond is another young player retiring before the age of 30. The struggling Eagles will look to replace him this off season.

Thurmond played in all 16 games for Philly in 2015, amassing an impressive 71 tackles, two sacks and three interceptions. He is only 28 years old, so perhaps his decision to leave football is not yet concrete certain, especially if a team were to offer him a significant contract as a free agent.

The 28-year old will be a free agent this season, and while the Eagles plan to try and resign him, talks have not yet occurred. At this point, it sounds like the Eagles and Thurmond will have negotiations near the combine.

Thurmond missed Wednesday's practice with a hamstring issue, but his return Thursday should indicate that he'll be fine for the Eagles' Week 13 match-up with the Patriots.
