Waiver-claim Barton won't report to Panthers after all

CHARLOTTE, N.C. -- Offensive lineman Kirk Barton decided not to report to the Carolina Panthers on Thursday, one day after the team claimed him off waivers.

Panthers coach John Fox said he believes Barton has decided to retire.

The Panthers waived reserve tackle Jason Capizzi on Wednesday to make room for Barton, who was released by the Denver Broncos earlier this week.

Barton, 25, is a former seventh-round pick by the Chicago Bears out of Ohio State. He has bounced around the league with several teams and played in one NFL game during the past two seasons.

Barton's decision left the Panthers a player short of the 80-man limit as they search for help with pass protection. The Panthers have allowed 11 sacks in two preseason games.
