Jahvon Quinerly decommitted from Arizona late Thursday -- less than four weeks after an FBI investigation suggested Arizona assistant Book Richardson provided impermissible benefits to the five-star prospect.

Quinerly is ranked 19th in the Class of 2018, according to 247Sports. The 6-foot point guard committed to Arizona on Aug. 8, 2017. Federal documents released last month allege Richardson orchestrated a $15,000 bribe to a prospect who committed to Arizona "on or about Aug. 9, 2017." Multiple sources have identified that prospect as Quinerly, who is from New Jersey. Consequently, it's unclear if he'll ever be eligible to play college basketball.

Richardson is one of 10 men arrested last month in an ongoing FBI investigation. The New York native has been on Sean Miller's staff since 2007 and is now facing fraud and corruption charges. He has been relieved of all duties at Arizona.
