Jontay Porter, the younger brother of Nuggets forward Michael Porter Jr., has been banned from the NBA after a league investigation found he disclosed confidential information to sports bettors about his health, limiting his own participation in one or more games for betting purposes. Porter, 24, was on a two-way contract with the Toronto Raptors, splitting time between the NBA team and its G League affiliate. The league investigation found that Porter also placed at least 13 bets on NBA games using an associate’s online betting account, according to a news release.
