DAVIE, Fla. (AP) - Miami Dolphins tight end Dustin Keller has been placed on injured reserve with a severe right knee injury that will force him to miss the entire season.
The move came Tuesday, three days after Keller was hurt in an exhibition game at Houston in which he tore several knee ligaments.
Miami filled Keller's roster spot by signing linebacker Nathan Williams, an undrafted rookie from Ohio State.
