[5] Gaither received significant playing time later in the 2006 season due to the struggles and injury of starter Matt McCoy.

Gaither got his first NFL start at weakside linebacker on December 4, 2006, on a Monday Night Football win against the Carolina Panthers.

He became the starter at weakside linebacker for the final 7 games (post and regular season) and finished with 58 tackles, 1 sack, and 1 interception.

Gaither was benched prior to the week 12 game at the Baltimore Ravens in favor of Akeem Jordan.

[16][17] The Atlanta Falcons signed Gaither, along with fellow Eagles teammate Jamar Chaney, on September 17, 2013, to replace the injured Sean Weatherspoon.
