Philadelphia Eagles linebacker Kiko Alonso suffered a concussion during a team practice session on Aug. 6 but was ultimately active for Week 1 against the Atlanta Falcons, confirmed the Eagles.

The 25-year-old was acquired from the Buffalo Bills during the offseason in exchange for LeSean McCoy. He missed the entire 2014 season due to a torn ACL.

The Eagles need the versatile and athletic Alonso in the middle of their defense. As a rookie in 2013, he proved that he's capable of doing great things, recording four interceptions and two sacks.

Kelly has spent a lot of time remaking the roster with the players he wants. Alonso was one of the first major pieces Kelly brought in, and the expectations for the linebacker are high in Philly.
