The N.F.L.’s 32 teams are some of the most valuable assets in sports, and they rarely change hands.

Yet just two days after the Carolina Panthers said they would investigate their owner, who was accused of what the team called “workplace misconduct,” an N.F.L. franchise — one of the most coveted businesses in the world — will be put on the open market by its longtime owner, Jerry Richardson. The only principal owner the team has ever had, Richardson has become the latest formidable figure to fall amid the rising sensitivity and anger around sexual harassment.

In recent months, accusations of sexual harassment have taken down titans in Hollywood and the media world, politicians in Washington, as well as celebrity restaurateurs. The issue finally arrived at the N.F.L.’s doorstep last week when a former wardrobe stylist for NFL Network leveled accusations of sexual harassment and sexual assault, leading to the suspension of six current and former employees.

Then on Friday, the Panthers said they had hired lawyers to look into accusations against Richardson, the team’s founding owner. On Sunday, the N.F.L. said it would take over the investigation. Hours later, Richardson announced he would sell the team in yet another scandal for the league amid an already tumultuous season that has included a nationwide debate over players protesting during the national anthem.

In a statement, Richardson said the sales process would commence after the season. He will not entertain any inquiries before the last game has been played. Richardson made no reference to the allegations against him or the league’s investigation into those claims.
