WNBA Coach Curt Miller Suspended for 'Offensive' Comment About Opposing Player's Weight

The WNBA has suspended Connecticut Sun head coach Curt Miller over an "offensive" comment he made about an opposing player during a game ... when he complained to a ref that she weighs "300 pounds."

The player he was talking about is Las Vegas Aces star Liz Cambage -- who says she weighs 235 pounds and was deeply offended by the comment.

Here's the backstory ... Cambage -- the #2 overall picking the 2011 WNBA Draft -- claimed Miller crossed the line when complaining to the refs about her during Sunday night's game in an effort to get a call against her.

Cambage claims she overheard Miller saying something like, "C'mon, she's 300 pounds!"

Cambage unleashed a fiery post on social media ripping Miller -- saying she's "very proud of being a big bitch" ... and "I will never let a man disrespect me, ever, ever, ever, especially a little white one."

Miller apologized Monday morning -- saying, "I made an inappropriate and offensive comment in reference to Liz Cambage's height and weight. I regret what I said in the heat of the moment and want to sincerely apologize to Liz and the entire Aces organization."

He added, "I understand the gravity of my words and have learned from this."

Now, the league has dished out punishment -- issuing a 1-game suspension against Miller and tacking on a $10,000 fine.
