Miami Dolphins tight end Dustin Keller suffered a right knee injury in the second quarter of Saturday's preseason game against the Houston Texans in Reliant Stadium.
At the very end of a 14-yard reception from QB Ryan Tannehill, rookie Texans safety D.J. Swearinger came up to make the hit on Keller, whose leg bent awkwardly as he went to the ground.
The AP's Tim Reynolds captured the ominous image below:
