NBA release:
"Portland Trail Blazers center Joel Freeland and Detroit Pistons forward Shawne Williams have been suspended one game without pay for head-butting each other. The penalties were announced today by Rod Thorn, President, Basketball Operations."
"Williams will serve his suspension tonight when the Pistons travel to Utah to play the Jazz. Freeland will serve his suspension on Sunday, March 15, when the Trail Blazers travel to Toronto to play the Raptors."
I was fine with Williams and Freeland getting fined or suspended for one game – as long as both received the same penalty. The NBA handled this well enough for me.
Williams will lose $11,164 as a result of the suspension.
