(AP) — Georgetown has opened its search for a new men's basketball coach, while Massachusetts is back in the market for a hoops coach.

John Thompson III has been dismissed by the Hoyas after the team posted back-to-back losing seasons for the first time since the early 1970s. The son of Hall of Fame coach John Thompson was 278-151 in 13 seasons at Georgetown, going to eight NCAA tournaments and reaching the Final Four in 2007.

The Hoyas went 29-36 in their final two years under Thompson and ended this season on a six-game losing streak. Their .438 winning percentage this season is the worst by the school since the 1971-72 squad went 3-23 under Jack MaGee, the year before Thompson's father took over the program.

Meanwhile, former Winthrop coach Pat Kelsey has backed out of an agreement to take over men's basketball at UMass. Minuteman athletic director Ryan Bamford said Thursday that Kelsey asked to be let out of his contract that was signed Tuesday, making clear that it was for "very personal" reasons.

UMass fired Derek Kellogg after the Minutemen finished 15-18 this season.
