Louis Delmas will return for his fifth season with the Detroit Lions.

 The free safety agreed to a two-year deal with the Lions on Friday.

 It’s a huge signing for the Lions. The team is better with a healthy Delmas on the field. His energy is contagious. He provides leadership for the defensive backs and the defense as a whole.

Delmas, who has been the starting free safety for the past four seasons, visited the St. Louis Rams and the San Francisco 49ers.

He underwent a physical in Detroit last week. His knees have been an issue the last two seasons. He missed eight games in 2012 and five games in 2011. He played 15 games in each of his first two seasons.

Reports are that the Rams were concerned about his knees and only offered him a one-year deal. 

 He will have a new partner. The Lions signed free agent safety Glover Quin on Wednesday. Quin started every game for the Houston Texans the past three seasons.
