ANDERSON, Ind. (AP) Indianapolis Colts center Ryan Kelly will miss Tuesday night's practice with an injured left shoulder.

The Colts' No. 1 draft pick sat out the final 90 minutes of practice Sunday and was back on the sideline Monday. Kelly is the biggest piece Indy has added to protect Andrew Luck.

Coach Chuck Pagano says he is considered day to day.
