Eric Reed does not use the word "revenge" or "bitter", but the Panthers' safety made it clear how he felt about the 49ers.
Reed returns to San Francisco on Sunday.  "I just don't forget," Reed said Wednesday, via ESPN's David Newton.
The 49ers did not re-sign Reed after the 2017 season. His good friend, quarterback Colin Kaepernick, has been playing since 2016.
Reed and Kaepernick settle their championship complaints, accusing the NFL of extorting them for taking a knee. during the national anthem in protest of social injustice. Reed continues to kneel for the anthem.
Reed did not leave with good feelings for the organization that made him 18th overall in 2013.
"Definitely the way he treated Colin. It's definitely the way I feel about me, "Reid said. "The way they manage the organization. Ask everyone who has been there and they will tell you the same. "
Reed disagrees with the 49ers' decision in 2017 to move him from strong safety to hybrid safety / line manager position to replace Navarro Bowman's attacker, whom the team released after he requested a trade.
"I remember they changed my position during the contract year," Reed said. "I remember they released Navarro, who led the league in secrets [in 2015] and asked me to play his position. I was told it was best for the team. I did not agree. I thought the NFL leader to handle it was the best for the team, but I did what I was told.
Reed, who has 37 games in six games, seems to have all the motivation he needs for Sunday.
