The University of North Carolina is challenging the NCAA’s jurisdiction to pursue charges in the school’s long-running academic fraud scandal and is holding off on self-imposed penalties.

The school on Tuesday publicly released its response to five potentially top-level NCAA charges, which include lack of institutional control. UNC acknowledged problems tied to irregular courses in a department popular with athletes on the Chapel Hill campus, but it argued that its accreditation agency – not the NCAA – was the proper authority to handle such a matter.

The school also said some charges were invalid because of an expired four-year statute of limitations, while arguing that it disagreed with the institutional-control charge.

The response is the latest procedural step that ultimately will lead to a hearing with an infractions committee panel.

 The NCAA has accepted Missouri’s self-imposed sanctions over infractions involving its men’s basketball program, but it tacked on a year of probation through August of next year.

The NCAA infractions committee panel’s findings over what it said were roughly $11,400 in improper inducements and benefits given to players and a recruit by two boosters were released Tuesday, nearly seven months after Missouri admitted NCAA violations dating to 2011.

The school announced in January that it was vacating its 23 wins from 2013-14, banning itself from the postseason last season and stripping itself of one scholarship last season and a second scholarship no later than 2017-18.

TENNIS

U.S. OPEN: Mother Nature will no longer be a problem at the U.S. Open.

The U.S. Tennis Association unveiled the new retractable roof over Arthur Ashe Stadium at the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York, on Tuesday.

The roof will be ready when the U.S Open begins on Aug. 29. The men’s final was delayed a day because of rain for five straight years from 2008-12.

USTA officials had long said that adding a roof over Ashe wasn’t feasible. But in 2013, architectural firm Rossetti drew up a workable plan.

The roof over the 23,771-capacity stadium is built to close or open in under seven minutes. It closed with ease during the demonstration, but it took three attempts to reopen it.

HOCKEY

NHL: A 21-year-old Buffalo woman has sued Sabres forward Evander Kane, saying he seriously injured her in the hotel room where he lives.

Documents filed July 1 in Erie County State Supreme on behalf of Rachel Kuechle Court say Kane met her in a bar, invited her to what he said was a party and then attacked her, causing cuts and bleeding that required multiple surgeries.

Kane had been cleared in March of any criminal charges after authorities investigated the Dec. 27 encounter initially described as a possible sexual assault.

His lawyer didn’t immediately respond to a request for comment but has denied any wrongdoing by his client.

BASKETBALL

NBA: The San Antonio Spurs signed two-time All-Star David Lee. Terms of the deal were not disclosed.

The 33-year-old won an NBA championship with Golden State in 2015. He has averaged 14.2 points, 9.2 rebounds and 2.3 assists over an 11-year career.
