Controversy
Arrest for assault

Spitting accusation
Following the 2019-2020 Divisional Playoff game between the Tennessee Titans and the Baltimore Ravens, Ravens' guard Marshal Yandaaccused Simmons of spitting in his face during the game. This was the first and only time in Yanda's 13-year NFL career that he had publicly accused another player of anything.[37][38]
"I do want to say another thing. No. 98 [Simmons] for the Titans - I had that guy spit in my face today. I just want to put him on notice in the media. I've never done this in my career, but I just want to let you know that there's a right way and a wrong way to play football. That guy did not do it the right way today."
— Marshal Yanda
The first time Simmons was asked about the event by a reporter during an interview before a practice the following week, Simmons did not directly deny the accusation.[39][40]
“I know what I did and I know what I didn’t do. At this point in time — today is Wednesday — I’m focused on the Chiefs right now and helping my team win. What I did this past game, what I didn’t do this past game, is not going to help us win this week, so I’m focused on what I can do to win, and what I will do to help get this win this Sunday.”
