Illegal Assist to Score violation, offensive player grabs rim while touching ball

“This play is an example of an illegal assist to score violation. The offensive player, Michael Porter Jr., clearly grabs the rim with his left hand while tapping the ball towards the rim with his right hand. This is an illegal assist to score violation, as an offensive player may not make contact with the ball and the rim at the same time in an attempt to score a basket. The ruling would be that no points can be scored, and the opposing team would inbound at the free throw line extended.”
