McCoy suffered a torn right Achilles tendon and will miss at least six months after having surgery Thursday to repair the injury.
The Seahawks announced the injury Friday, confirming an earlier report from Mike Garafolo of USA Today.
McCoy, 25, was Seattle's backup tight end last season, playing behind Zach Miller while seeing plenty of time in two-tight end sets. After struggling with drops, penalties and injuries during his first two seasons, McCoy finished 2012 with career highs in receptions (18), receiving yards (291) and touchdowns (3). He appeared in all 16 regular-season games and both of Seattle's playoff games.
McCoy, a sixth-round pick in 2010 out of USC, is entering the final year of his contract.
His injury clears the path for rookie Luke Willson to be Seattle's No. 2 tight end. Seattle chose Willson in the fifth round out of Rice, and he was among the standouts during the team's rookie minicamp earlier this month.
Darren Fells, Sean McGrath, Cooper Helfet and Victor Marshall are the other tight ends on the Seahawks' roster.
