Broncos CB Porter leaves game with concussion

Denver Broncos cornerback Tracy Porter left Sunday's game against the Cleveland Browns in the first quarter with a concussion.

The team announced Porter will not return.

Porter collided with Browns wide receiver Josh Gordon after a short reception. Porter stayed on a ground briefly before walking toward the sideline. He then went to the locker room after talking with team trainers.

It was Porter's first game since missing nine straight because of seizures.
