The Colts placed veteran defensive end Kendall Langford on their injured-reserve list Saturday.
Langford started the season’s first seven games before suffering a knee injury. He had played in 135 consecutive games, the most by any active NFL defensive lineman, before suffering the injury.
The Colts promoted cornerback Christopher Milton from the practice squad to fill Langford’s roster spot.
Milton is an undrafted rookie who will likely play on special teams for the Colts. He blocked two kicks last season at Georgia Tech and at the time was FBS football’s active leader in blocked kicks.
