Georgia Tech has made Cuonzo Martin its prime target for its head-coaching vacancy, multiple sources told The Chronicle on Wednesday afternoon.

The Yellow Jackets have “zeroed in” on Martin and are “very interested” in working out a deal with him, one source with knowledge of the situation said. This comes after multiple reported possibilities for Georgia Tech’s opening have been removed from consideration.

Duke assistant coach Jeff Capel withdrew himself from the search Sunday, according to CBS Sports. Valparaiso’s Bryce Drew has agreed to become the Commodores’ head coach.

Martin, 44, is under campus review into whether he fulfilled his responsibility as a mandatory reporter of sexual-harassment allegations against assistant coach Yann Hufnagel. The university informed Hufnagel of its intention to fire him last month.

Martin has been interested in pursuing opportunities elsewhere “for some time,” a source close to him said.

Martin, who is still working under his original offer sheet, is an intriguing option for the Yellow Jackets for several reasons. He has a proven track record recruiting the South, including last spring’s addition of five-star recruit and Atlanta-area native Jaylen Brown. His Cal teams have performed well in the classroom, and Georgia Tech is a similarly rigorous academic university. He also boasts two NCAA Tournament appearances in three years.

Georgia Tech fired head coach Brian Gregory on March 25. In five seasons in Atlanta, Gregory went 76-86 (27-61 ACC). His lone postseason appearance came this year when, after winning six of eight games, the Yellow Jackets qualified for the NIT.

If he returns to Cal, Martin could oversee a rebuild. The Bears lost point guard Tyrone Wallace from a team that was upset in the first round of the NCAA Tournament by 13th-seeded Hawaii. Though they have yet to make a decision about their future, Brown and forward Ivan Rabb are widely projected as lottery picks in June’s NBA draft.

The lone pledge left in Cal’s 2016 recruiting class is unrated junior-college point guard Dontae Coleman, a native of Augusta, Ga. Martin would have a second opening on the Bears’ staff if associate head coach Tracy Webster leaves for Wisconsin-Milwaukee’s head-coaching vacancy, a position for which he is a reported front-runner.
