Over the weekend, the Philadelphia Eagles lost wide receiver Jeremy Maclin for the season to a torn ACL. They started their week by losing another player with a similar injury, as linebacker Jason Phillips had to be carted off the practice field Monday with what was later confirmed to be a torn ACL, according to Les Bowen of the Philadelphia Daily News.

The Eagles signed Phillips this offseason after the linebacker spent the past two years with the Carolina Panthers. While he wasn’t expected to be a starter with Philly, he was viewed as an important special teams player.

Phillips avoided significant injury last season, as he was able to play in all 16 games for the Panthers, starting twice. He’s now slated to join Maclin on the sideline for the entire 2013 campaign.
