The Panthers officially announced they've re-signed Cole - an unrestricted free agent - to a one-year contract. Financial terms were not released Wednesday.
The return of Cole means the Panthers have kept their entire defensive line rotation from last season intact. Cole started 13 games last season for the Panthers second-ranked defense in 2014 and helped the team to the NFC South championship. Cole, whose role is primarily to take up blocks up front, had 15 tackles, one sack and three quarterback pressures. He missed all of the 2011 and 2012 seasons with an ankle injury.
