The NFL said through a spokesman that it will conduct the investigation and expects to retain outside counsel, but declined further comment.
While Richardson tries to behave as if the news of the past 24 hours is just coincidental to the shocking allegations against him, which Sports Illustrated reported were both sexual and racial in nature, the Panthers are thrown into upheaval.
The Panthers originally announced Friday that the team opened an investigation into the allegations, which have not been revealed because of the nature of the issue.
While his statement claimed that the team won't be up for sale until the end of the season and inquiries wouldn't be entertained until the "last game is played", it has people chomping at the bit.
"I'm very sad", Jones said after the Cowboys' 20-17 victory against the Oakland Raiders. He said he spoke to players again on Monday, and that he hopes the team can stay in Charlotte.
"There has been no greater mission or goal in my life than to have brought an National Football League franchise to Charlotte", Richardson said in a statement. "He took what he made in his short time in pro football and turned it into a great business and then used that to get the Carolina franchise".
Richardson has owned the Panthers since 1993, when they became the league's 29th team and its first expansion franchise in almost two decades. "I think it's time for that", he said.
The Panthers began play in 1995 but have never delivered on Richardson's promise of winning a Super Bowl. And I really admire him. The reason I did was because of the news that came out last night. "I don't take that lightly", Quarterback Cam Newton said. "I've got some boys that want me to, and so we may - on a weak moment - we might would do that", Smith said.
No word yet on where things go from here, but we'll keep you posted. He's had a heart transplant.
