Sports Illustrated published a report on December 17 alleging that Richardson sexually harassed multiple women and used a racial slur toward a team scout.
The next step for Tepper. league owners would vote to approve the sale later this month - it's pretty much just a formality at this point.
Tepper, who is said to be worth about $11 billion, will also have to divest himself of his stake in the Steelers as part of the deal. He attended Peabody High School and earned degrees from Pitt and Carnegie Mellon. National Football League owners still must approve the sale.
Prior to the 2016 presidential election, he said in an interview with CNBC, "You have one person with questionable judgment and the other person may be demented, narcissistic and a scumbag".
The proposed Panthers sale highlights an upward trajectory for the value of professional teams in major sports. Carolina has reached the Super Bowl twice, including in 2015, but has never won.
Sports Illustrated reported accusations of sexual harassment, including inappropriate touching by more than one woman and a racial slur made to a team scout. The question now turns to what kind of an owner Tepper will be, and whether he will put strict guidelines and safeguards in place to ensure the safety and happiness of all employees. In a 2010 New York Magazine profile, the publication described his offices: "Tepper has a pair of brass testicles".
The latest SI story that placed a more human touch on the allegations has put the league in a position where it likely has to respond with some action.
