MIAMI --Rookie wide receiver Dwayne Harris left for the locker room in the second half of Thursday night's preseason finale and didn't return after getting knocked woozy.
Even so, he probably solidified a roster spot.
Harris caught one pass for 11 yards and zig-zagged his way through the Dolphins' special teams for a 25-yard punt return.
The 2011 sixth-round pick has been battling for a backup job behind Miles Austin, Dez Bryant, Kevin Ogletree and possibly Jesse Holley.
Harris said afterward he felt OK.
