Reid was widely considered one of the best free agent safeties on the market -- but he believed he was being blackballed, like Colin Kaepernick, for taking a knee during the national anthem at NFL games.

Eric and Colin were teammates on the 49ers. They're still good friends and are using the same lawyers -- Mark Geragos and Ben Meiselas -- to go after the NFL for collusion.

Reid is a former Pro Bowl safety who racked up 67 tackles and 2 interceptions last season -- and many believe he should have easily gotten a roster spot in 2018 based on his talent.

Reid, 6'1" and 215 pounds, played the first five seasons of his NFL career with the San Francisco 49ers after being selected by the team in the first round (18th overall) of the 2013 NFL Draft.

“Eric has been a starting safety in the NFL and has played at a high level throughout his career," Panthers GM Marty Hurney said.

"After we put (safety) Da’Norris Searcy on injured reserve, Ron (Rivera) and I discussed our options, and Eric was at the top of our list. He is a physical safety with good ball skills and play-making ability."

Reid is already at the team facility.
