Detroit Lions safety Louis Delmas had surgery on his left knee, the team confirmed Wednesday.
Delmas has started 41 games for the Lions in his three-year career. The 25-year-old had two interceptions as a rookie in 2009, including one that he returned 101 yards for a touchdown.
Last season, Delmas started 11 games. He suffered an MCL sprain in the team's Thanksgiving Day game with the Packers, needed surgery and missed Detroit's final five regular season games. (The Lions' news release says his current injury is unrelated to the injury from last season).
Delmas was back for Detroit's playoff game with the Saints, but the Lions' season ended in a 45-28 loss. Detroit's secondary has already taken a hit this offseason. Cornerback Aaron Berry was released after two arrests. Berry had been expected to start.
