PHILADELPHIA (CBS) -- Jason Peters is still working hard.

The 35-year-old future Hall Of Fame left tackle tore his ACL ending his season on October 23rd. Some have speculated that it may be a career-ending injury for the nine-time Pro Bowler.

Peters' teammate, Chris Maragos -- who also suffered a season ending injury -- tweeted this video of JP working out.

Last week, Eagles veteran Darren Sproles -- who also suffered a season ending ACL injury -- was recorded running sprints.

Nick Foles, who replaced Carson Wentz -- who, you guessed it, also suffered a season ending ACL injury -- talked about how the Eagles are playing for the injured players.
