The Lions announced four roster moves on Monday including the release of defensive tackle Vaughn Martin who they signed as a free agent in March.

Martin was a starter in San Diego in 2011 and 2012, but was released by the Miami Dolphins in November following hernia surgery. When he was signed, it was expected that he would back up Ndamukong Suh and Nick Fairley.

Defensive end Kourtnei Brown, who was claimed off waivers from the Buffalo Bills in April, was cut on Friday.

Replacing them on the roster are wide receiver Cody Wilson and defensive end Kalonji Kashama.

Wilson, who played at Rochester Adams and Central Michigan, was on the Lions’ practice squad last season. He was released on May 12 following the draft. Wilson's father, Dave, is the team's long-time chaplain. 

Kashama, who started for three years at Eastern Michigan, took part in the Lions’ rookie camp in May. He is from Brampton, Ontario.
