Koa Misi gets deal through 2017

MIAMI -- The Miami Dolphins signed outside linebacker Koa Misi to a four-year contract extension, the team announced Saturday.

Misi, who was in the final year of his rookie contract, is now signed with the Dolphins through 2017.

This is a significant commitment for the Dolphins to their linebacking corp. Miami signed veteran linebackers Dannell Ellerbe and Philip Wheeler to sizable contracts last March in free agency. Adding Misi's extension this weekend means the Dolphins have locked up their three starting linebackers for the foreseeable future.

Misi started 14 games for the Dolphins last season and recorded 65 tackles and 3.5 sacks. The Dolphins will open the season Sunday with a road game against the Cleveland Browns.
