Video: Horrific knee injury inflicted on Miami Dolphins player in pre-season game

Miami Dolphin’s tight end Dustin Keller’s season is over, after his knee buckled in a most sickening way during a warm-up game against the Houston Texans.

With the NFL season being so short, it is very, very cruel to get a bad injury so close to the big kick-off. So when the Miami Dolphins begin their campaign, they will have to do so without the services of tight end Dustin Keller, who suffered a sickening knee injury on Saturday. Miami QB Ryan Tannehill found Keller with a short pass but the Dolphin was lined up by Texans safety DJ Swearinger (great name) who planted his helmet right on Keller’s knee. This caused Keller’s knee to buckle unnaturally, tearing ALL the major ligaments in the joint. He now faces a long road back to fitness, and he will play no part for the Dolphins this season. Swearinger came in for some criticism for the hit but the rookie explained it thus: "I was making a hit playing football. In this league you’ve got to go low. If you go high you’re going to get a fine." Head injuries are a massive issue in the NFL but does that make going for the knees a legitimate move, even if currently legal?
