Crowder took exception to Perkins pick and things got testy.

Perkins appears to throw something that likes like a punch, albeit remarkably slow and lazily, which caused even more scuffling. Perkins was issued a flagarant 1 for the big shoulder check and both he and Crowder were issued technical fouls.

The Boston fans, who supported this type of behavior from Perkins when he was a member of the Celtics, were not pleased at all.
