Houston, TX (Best E Casino) - Denver Broncos linebacker Louis Green left the field on a stretcher with a neck injury and a concussion in the first quarter of Saturday's preseason game against Houston.

Green collided with teammate D.J. Williams as the two converged on a tackle of Texans tight end Owen Daniels, who caught a short pass on the play.

He laid motionless on the field for several minutes as medical staff rushed to check on him. Green was strapped to the stretcher and was moving his fingers and hands when he was rolled off the field.

Green was taken to a hospital for further evaluation.

Green had replaced Boss Bailey, who sprained his right ankle and limped off the field on the Texans' second play from scrimmage.

Starting his fifth season, the 28-year-old out of Alcorn State played in all 16 games for Denver last season and finished with nine tackles.
