For what it’s worth, bucks can protest this entire game if they lose

Nick Richards isn’t allowed to play in this game anymore, and Lamelo wasn’t allowed to be the FT shooter

If the offended player is injured, other than as a result of a flagrant foul or unsportsmanlike conduct, or is ejected from the game and cannot attempt the awarded free throw(s), the opposing coach shall select, from his opponent’s bench, the replacement player. That player will attempt the free throw(s) and the injured player will not be permitted to re-enter the game. The substitute must remain in the game until the ball is legally touched by a player on the court.
