The response to allegations against Richardson - one of the NFL's most powerful owners and the only current owner who's played in the league - moved with astonishing speed.
Medina-Tayac also called the online hoax "a culture jam" tactic and said the group effectively changed the team's name on Wednesday with the websites.
He added that the sale of the Panthers, who joined the National Football League in 1995, would not begin until the last game of the season had been played. "Let's make it happen!" he wrote.
"There has been no greater mission or goal in my life than to bring an National Football League franchise to Charlotte", Richardson said in his statement. Gauging how much the franchise would fetch is hard, given professional football is still far and away the best-rated American sport, but has seen decreased ratings and increased polarization due to people like Kaepernick, who knelt for the national anthem to protest police brutality and racism in the U.S. The last NFL team to change hands was the Buffalo Bills, who were sold for $1.4 billion in 2014.
Richardson had previously said that the team would be sold when he died. On Friday the Panthers announced that they had hired attorneys to investigate allegations against the organization's 81-year-old founder.
