DAVIE, Fla. -- Miami Dolphins middle linebacker Zach Thomas will miss Sunday's game against the New York Jets after tests revealed he has a mild concussion.
With Pro-Bowler Thomas on the sidelines, outside linebacker Channing Crowder would start in the middle, and Donnie Spragan would likely move into the lineup on the outside. Thomas might be available to play next week.
Thomas played every snap in Miami's loss Sunday to Dallas but said he felt lightheaded in the locker room after the game. He complained of a migraine this week and missed practice for the third day in a row Friday.
The game will be only the 14th Thomas has missed in his 12-year career.
