Dolphins TE Dustin Keller (knee) carted off


The Miami Dolphins may have suffered their first major injury of the preseason.

Dolphins starting tight end Dustin Keller suffered what could be a significant knee injury in the second quarter of Miami’s exhibition game against the Houston Texans. Keller was hit on his right knee as soon as he landed on a reception. Keller's leg hyperextended and he clutched his knee in pain.

Keller couldn't put weight on his leg and the team had to cart him off the field. Those are two bad signs. Miami was counting on Keller, a free-agent signing, to provide stability and production on offense. He already had a good rapport with Dolphins quarterback Ryan Tannehill.

Keller had an injury-plagued year with the New York Jets last season. If he misses significant time this season, Miami will have to rely on young backup tight ends such as rookie Dion Sims, Michael Egnew and Charles Clay.
