Oakland A's catcher Bruce Maxwell was arrested and charged with aggravated assault with a deadly weapon on Saturday.
TMZ reports that Maxwell, 26, was arrested at 6:08 p.m. at his Scottsdale, Arizona home after cops say he pulled a gun on a female food delivery driver.
Police did not reveal what provoked the incident.
Maxwell is best known as the only Major League Baseball player to kneel during a game -- apparently in a show of solidarity with NFL players who kneel during the National Anthem in defiance of President Trump.
Maxwell is currently in jail awaiting an initial hearing.
Last week, Maxwell made headlines again when he claimed he was denied service at an Alabama restaurant by a "pro-Trump waiter" who objected to him kneeling during the Anthem.
His story was later discredited by the restaurant's manager who told a reporter that Maxwell's two friends -- including an Alabama state senator -- were denied alcohol because they had expired IDs.
Anne Whalen, a manager at Keegan's Public House restaurant in Huntsville, said Maxwell was the only one served alcohol because he produced a valid ID.
She said the baseball player was "mistaken" about refusal of service.
