Tim Couch's return to the NFL lasted nearly three weeks.
The Jacksonville Jaguars released the former top draft pick Saturday after a handful of practices and one preseason game.
Couch, who hadn't played in the NFL since the 2004 preseason, wanted a chance to revive his career following two shoulder operations.
The Jags signed him to a two-year deal on July 29, but Couch failed to make an impression in training camp. He was 2-of-4 passing for 11 yards last week at Miami and was sacked twice. The overall No. 1 pick by Cleveland in 1999 also missed practice this week with a sore back.
