Duke University on Tuesday said its human resources department is reviewing the women's basketball program, which has seen three players leave the team since the middle of the 2015-16 season.
The school issued a statement Tuesday saying coach Joanne P. McCallie is "aware of the evaluation and eager to assist."
"The welfare and success of our student-athletes are among Duke's highest priorities," the university's statement said. "This effort is led by a Duke human resources professional outside the athletics department."
Two players, Azura Stevens and Angela Salvadores, announced after the season that they were leaving the program. Guard Sierra Calhoun left midway through last season, transferring to Ohio State.
School spokesman Jon Jackson declined to comment to The Associated Press when asked why Duke is reviewing the program. McCallie did not return a text message seeking comment.
Sources with knowledge of the situation told espnW that the evaluation is examining coach McCallie's tenure at Duke, which began in 2007, including her treatment of players and staff.
Stevens, who averaged 18.9 points and 9.5 rebounds this season as a sophomore, is transferring but has not announced her destination.
Salvadores, a 5-10 guard from Spain, played one season at Duke and is returning to Europe to pursue a professional career. She averaged 8.7 points and 3.3 assists.
Duke was 20-12 this season and missed the NCAA tournament for the first time since 1994.
