Memphis Grizzlies forward Matt Barnes was handed a one-game suspension for trying to enter the Milwaukee Bucks' locker room after getting ejected on Thursday.
After Bucks forward John Henson blocked a Barnes shot, the two exchanged words.
Henson was slapped with a double-technical foul for taunting and was ejected.
Minutes later, Barnes was ejected and headed to the visiting locker room at the Bradley Center in Milwaukee, where the Bucks had a 96-86 win.
"I got led into the wrong room," Barnes said, via CBS Sports. "So once I realised I wasn't where I was supposed to be, I left and went into my locker room."
The NBA was not convinced, so Barnes will miss Saturday's clash against the Los Angeles Clippers.
