Indianapolis Colts rookie safety T.J. Green hobbled off the field with a right knee injury in the second quarter of Sunday’s home opener against the Detroit Lions at Lucas Oil Stadium.
The Colts announced before halftime the rookie had suffered a right knee sprain, then advised early in the third quarter that he would not return.
Green, the Colts’ second-round draft pick out of Clemson, ran toward the middle of a mass of players and the impact with the outside of the group caused his leg to buckle. He pointed to the inside of his right knee while laying on the Lucas Oil Stadium Field turf.
The Colts were already without several key starters, including second-year safety Clayton Geathers, who was supposed to become a full-time starter but has been sidelined by a broken foot bone suffered during an offseason workout. He missed all of training camp. That forced Green into a starting role for his NFL debut.
Colts inside linebacker D’Qwell Jackson, the NFL’s No. 2 tackler a year ago, stayed down with an undisclosed injury after a Lions run with 1:46 remaining in the first half. The Lions then scored again to push their lead to 21-3.
