Eric Crouch has quit the NFL for the second time in 11 months.

　　The 2001 Heisman Trophy winner from Nebraska left the Green Bay Packers on the eve of full-squad workouts, which began on Tuesday. He had hoped to win a job as one of Brett Favre's backups, but coach Mike Sherman said he had little chance at beating out the three QBs ahead of him in that race.

　　Crouch sat out last season after the St Louis Rams drafted him in the third round and tried to convert him into a wide receiver.

　　He was set to play quarterback in the Canadian Football League, which he thought could be a springboard to a career as an NFL quarterback, when the Packers claimed him off waivers this spring.

　　He left camp on Monday night after speaking with Sherman and the Packers placed him on the reserve/retired list, retaining his rights.

　　"We really didn't get into detail. He just said for personal reasons he didn't want to continue. I said OK and we'll leave it at that," Sherman said.

　　"It's disappointing that it didn't work out for us and for him. But we didn't have a whole lot invested in him. He's a good kid, we wish him well."

　　The Packers had hoped Crouch be a return specialist this year and learn the West Coast offense by next season as a quarterback.

　　But after claiming him on April 23, the Packers signed Akili Smith, who will vie for the backup quarterback job with incumbent Doug Pederson and second-year pro Craig Nall.

　　Crouch, who last worked as a quarterback in the option offense with the Cornhuskers, didn't make much of an impression as a kick returner, either.

　　Crouch told Omaha television station KPTM on Tuesday night that he's probably through playing football.

　　"Yeah, I think so," Crouch said. "I'm ready to move on. I've been a football player for a long time. I've loved it. It's been a lot of fun."
