One of the country’s most powerful basketball programs is being probed after a woman alleged a player raped her two decades ago.

Duke announced Saturday it will investigate the allegations made by Meredith Watson, who said a day earlier that a former Blue Devils player raped her in 1999. Watson is the second accuser of Virginia Lt. Gov. Justin Fairfax, saying he sexually assaulted her on Duke’s Durham, N.C., campus in 2000, when they were students.

The identity of Watson’s alleged attacker from the team is not known. Legendary Duke coach Mike Krzyzewski said he could speak of the veracity of the claims but was taking them seriously.

“I think there was an allegation made, right?” Krzyzewski told reporters Saturday after Duke’s 81-71 win over Virginia. “So, I’m not sure if it’s true or not, but there is an allegation. I did not find out about until late [Friday] night. I had no knowledge. That [allegation] is hugely important, and our university will take care of whatever actions and give whatever information that is needed.”

The 1998-99 Duke basketball team was one of the iconic program’s best, losing to UConn in the national title game in a season in which Krzyzewski was the Naismith College Coach of the Year.

“Ms. Watson was raped by a basketball player during her sophomore year at Duke,” Watson said in a statement from her attorney, via ESPN. “She went to the Dean, who provided no help and discouraged her from pursuing the claim further. Ms. Watson also told friends, including Justin Fairfax.”

Duke said it only learned of the allegations through the media.

“Coach Krzyzewski confirms that he had no knowledge of the alleged conduct from 1999,” the school said in a statement. “The university is looking into the matter and will have no further comment at this time.”
