Frank Reich, the Colts' head coach, told reporters last week that Darius Leonard, a linebacker, had undergone surgery on his back to treat an injury.

Reich stated that Leonard was expected to be available for the start the regular season. However, Leonard might not miss too much practice.

Zak Keefer, of TheAthletic.com says Leonard's ankle problem from last season was lingering due to a related issue in Leonard's calf. The nerve issue in Leonard's back caused the calf problem. Leonard underwent surgery to fix the problem with his back.

Keefer says that Leonard is expected to be available for practice at the beginning of training camp, or when camp starts in late July.

Leonard played 16 games last year despite lingering injuries and had 122 tackles. Leonard was named All-Pro for the 3rd time, and was also selected to his 3rd consecutive Pro Bowl.

Leonard also had four interceptions and eight forced fumbles, which were league-leading.
