We'll probably never know what Kevin Garnett said to Carmelo Anthony Monday night, but Doc Rivers flatly denies the Cheerios comment.

"I know what's being reported did not happen," the Celtics coach said Thursday on WEEI radio in Boston. "I know that as a fact."

Anthony, who was suspended for last night's 81-76 loss at Indiana, declined to spell out exactly what KG said during Monday's game.
