Seattle Seahawks wide receiver Isaiah Stanback was carted off the field on Saturday night, and Eric Williams of the Tacoma News Tribune reports the former University of Washington quarterback has a torn Achilles tendon and will likely miss the 2010 season.

Stanback is the second Seahawks player to tear an Achilles tendon this week, joining first-year linebacker Anthony Heygood, who tore his during warm-ups on Thursday.

Claimed off waivers from the New England Patriots on June 1, Stanback was a fourth-round pick (103rd overall) by the Dallas Cowboys in 2007. The 6-2, 208-pound Stanback has appeared in 16 games, including two starts, over the last three seasons, catching 5 passes for 46 yards and averaging 22.7 yards on 14 kick returns.

The Seahawks' lone practice on Sunday will take place at Husky Stadium, where Stanback played from 2003-07, piling up 4,662 yards of total offense with 33 touchdowns.
