I didn't catch any audio, if there was any to hear. Initially, Hibbert looked to have lower his shoulder into Lee and Hibbert didn't get called for an offensive foul. But Lee didn't help his case any by blatantly pushing Hibbert under the basket. Then the shoulder bumps started. What gets me is Curry kept trying to tie up Hibbert even though Hibbert had backed away from the crowd. I think both teams will lose a couple of players and as SilverSpur pointed out above, when you start rubbing elbows in the middle of paying customers, the NBA starts playing Sherlock Holmes with the magnifying glass. Cha-ching --- big time!!
I dream of a day when a chicken can cross the road without having their motives questioned.
