The Arizona Wildcats have suffered their first recruiting setback since the FBI investigation came to light on Tuesday, and it's a big one:

Five-star Canadian forward R.J. Barrett, the top-rated player in the class of 2018, confirmed via Twitter that he is no longer considering the Wildcats. He posted a final three schools of Oregon, Duke and Kentucky — schools not implicated in the federal — meaning he dropped the UA and Michigan.

Barrett visited Arizona last weekend, just before UA assistant coach Book Richardson was arrested on suspicion of federal bribery and fraud charges on Tuesday.

The commitment of UA recruit Jahvon Quinerly also appears shaky at best if he is found to have taken money from an agent through Richardson, as the federal complaint alleges.

However, the UA's two other recruits, Brandon Williams and Shareef O'Neal, have remain committed to the Wildcats — Williams' dad says he's "100 percent" committed and O'Neal's Twitter page refers to him as an Arizona commit.
