Bryce Hall seems to have put his boxing skills to the test in Sin City, punching a nightclub security guard in the head, and it's all on video -- an incident that could land him in some legal trouble.
TMZ obtained the footage, shot Friday night in Las Vegas outside XS nightclub at the Wynn, showing the TikTok star getting physical with security -- including a punch to the side of the guy's head.
Law enforcement sources tell TMZ ... LVMPD responded to a call from XS and police ended up citing Bryce with two counts of battery and one count of trespassing, all misdemeanors.
