Indianapolis Colts wide receiver Austin Collie has been carted off the field in the third quarter of Sunday's game against the Jacksonville Jaguars with a sprained knee. The team has ruled out his return for the game, according to Kareem Copeland of NFL.com.

After hitting the turf hard at Lucas Oil Stadium, the crowd fell silent as Collie was motionless on the ground. The wide receiver has been diagnosed with multiple concussions during his career, so there was obvious concern that he had suffered another head injury.

The Colts have said that Collie's injury is a knee sprain, though, which is a bit of a relief. After suffering a concussion during the preseason, Collie was making his season debut on Sunday, but now it's unclear how long he'll be on the sidelines.
