Seattle Seahawks tight end Anthony McCoy suffered a torn Achilles tendon during organized team activities this week and underwent surgery on Thursday repair the injury, a person informed of the diagnosis told USA TODAY Sports.

The person, who spoke on condition of anonymity because the team hasn't confirmed the injury, said McCoy will miss at least six months.

Though McCoy isn't the Seahawks' No. 1 tight end, he saw plenty of action in double-tight sets along with Zach Miller last year. McCoy played in all 18 of the team's games last season, with seven starts. He had 18 receptions for 291 yards and three touchdowns in the regular season. The former sixth-round pick also played in all 16 games in 2011 and was credited with nine starts.
