Ravens lose TE Benjamin Watson (torn Achilles) for season

BALTIMORE -- Baltimore Ravens tight end Benjamin Watson is out for the season after tearing his Achilles on the first play of Saturday's preseason game against the Detroit Lions.

Watson, who was the Ravens' first free-agent signing this offseason, suffered the injury when he tripped over his feet while running a route over the middle. He was carried off the field and couldn't put any weight on his right leg.

Watson, 35, was coming off a career year with 74 catches for 825 yards receiving and six touchdowns. He had been one of the more durable tight ends, missing only one game in his past four seasons.

The Ravens are down to one healthy tight end with experience: Crockett Gillmore. Baltimore has been without Dennis Pitta (fractured finger) and Maxx Williams (undisclosed) for most of the preseason.
