CHARLOTTE, N.C. - Facing a growing investigation that accuses him of sexual misconduct and using racist language at work, Carolina Panthers owner Jerry Richardson announced Sunday that he will sell the NFL team after the season. The team announced on Twitter that Richardson is selling the team, linking to a five-paragraph letter by the franchise's only owner. "I believe it is time to turn the franchise over to new ownership," Richardson wrote, saying he wouldn't begin discussions until after the season. The Panthers, who lost in the Super Bowl in 2016, are in playoff position. "I hope everyone in the organization, both on and off the field, will be firmly focused on one mission: to play and win the Super Bowl," said Richardson, 81.
