MIAMI -

According to ESPN, the Miami Dolphins will be without tight end Dustin Keller for the entire 2013 season.

Keller suffered a gruesome knee injury during the first half of the Dolphins preseason game against the Texans.

The tight end was carted off the field.

The ESPN report says that Keller tore his ACL, MCL, and PCL. 

The Fins signed the former New York Jet to a one-year contract.

Miami will now need to find more help at that critical offensive position.
