Grimes went out in the fourth quarter of Atlanta's 40-24 win at Kansas City in the season opener. Coach Mike Smith announced Monday the cornerback will need surgery, costing Atlanta one of its best defensive backs. Grimes was a Pro Bowler in the 2010 season and got the franchise tag this past offseason when he couldn't agree on a new contract, receiving a salary of $10.2 million.
