Rayner handled kickoff duties for the Colts last year until the final three games of the season when he was replaced by Cortez. Rayner will compete for the kicking duties in Green Bay against Billy Cundiff, who was signed as a free agent this off-season.
The 6-foot-2, 205-pound Rayner kicked off 82 times for the Colts and averaged 61.5 yards per kick, but had only one touchback. Opponents averaged 22.3 yards per return on his kickoffs.
Rayner was a sixth-round pick out of Michigan State who spent 14 games on the Colts' roster last season. He missed on his only field-goal attempt, a 59-yarder against the San Diego Chargers.
The Chicago Bears also placed a claim on Rayner, but he was awarded to the Packers because the Bears had a better record than the Packers last year.
