Conor McGregor has been accused of raping a woman at Game 4 of the NBA Finals earlier this month ... but the UFC star says the allegations are not true.
According to demand letters, authored by attorney Ariel Mitchell, that were sent to McGregor, the NBA and the Miami Heat this week ... the incident happened just after the Nuggets had won, 108-95, on June 9 at the Kaseya Center in Florida.
McGregor played a big part in the entertainment at the game -- he sat in courtside seats -- and even participated in a halftime skit where he punched a Heat mascot multiple times while promoting his Tidl Sport recovery spray.
