Broncos RB Phillip Lindsay ruled out with concussion after taking helmet-to-helmet hit

DENVER -- Denver Broncos running back Phillip Lindsay's star-crossed season continued Sunday when he left the game against the Kansas City Chiefs with a concussion.

Lindsay, who had 79 yards rushing on his nine carries in the game, absorbed a helmet-to-helmet from Chiefs safety Daniel Sorensen on 5-yard run with just over two minutes remaining in the first half.

Lindsay was groggy as he got to his feet, was helped to the injury tent on the Broncos' sideline and after a brief check from the team's medical staff was taken to the locker room. Lindsay had missed three games and most of a fourth with a toe injury to open the season.

He had returned to the lineup last week against the New England Patriots and provided a spark to the offense with 101 yards on 23 carries. It meant he had rushed 180 yards on his last 32 carries before Sunday's injury.

Lindsay will not enter the league's concussion protocol and will be held out of practice until he is cleared.
