Lucas originally joined the club near the end of its organized team activity sessions in June. He spent training camp with the Packers, catching two preseason passes for 22 yards, then was re-signed to the practice squad Sept. 5. Originally signed as a nondrafted free agent by the Titans in 2004, he also had a stint in the Arena Football League.
Butler, a 6-foot, 195-pound wide receiver out of Northwestern Oklahoma State, also spent 2005 training camp with the Packers, but did not catch a pass in preseason action. He had been out of football since the team waived him in its final roster reduction.
Wallace, also a wide receiver, had signed Oct. 25 as a free agent after Robert Ferguson sprained his left knee at Minnesota on Oct. 23. Wallace was in on a few plays at Cincinnati Oct. 30 but did not play Sunday against Pittsburgh.
