Per the Associated Press, Mack accused Smith of "grabbing his private parts" during Sunday's game. "I don't think he should be able to do that," Mack said Monday. "I'm still fired up about it."
It came on a third down in the second quarter. Apparently, Mack started chasing Smith towards the Chiefs sideline but backed up once the Cleveland punt team started coming onto the field.
Later in that quarter, perhaps out of frustration, Mack pushed Derrick Johnson after the play was over resulting in a personal foul.
For his part, Smith denies it happening.
"I don't have no comment," Smith said. "I don't recall doing anything like that. I'm not known for being a dirty player or anything like that, so I don't know what that was all about."
So who's right?
We'll let Friday Fine Day decide that one: If Smith is fined, he's guilty. If he isn't fined, he's not guilty.
