The incident between Beilein and Thompson took place late in the third quarter Thursday night. Following Matthew Dellavedova’s steal, Thompson received a pass and threw down a two-handed breakaway dunk that put the Cavs ahead by nine. But as the Spurs called timeout and players sauntered toward the bench, Thompson was still fuming. Dellavedova, one of Thompson’s longest-tenured teammates, tried to restrain the veteran. But it didn’t work. Thompson was seen on camera shouting something at Beilein.
