[15] On November 4, he was suspended four games by the NFL for violating the league's personal conduct and substance abuse policies for his offseason arrests.

[21] On February 15, 2019, he was arrested for a second time and charged with misdemeanor battery for an altercation triggered after he grabbed a phone from a neighbor in Miami.

[22] The charges underlying his third arrest on April 4, 2019, stemmed from a March 12, 2019, incident in which Walton fled on foot from his rented car after police tried to pull him over.

Authorities found a rifle in the car and accused Walton of carrying a concealed firearm, resisting an officer without violence, possession of marijuana, and reckless driving.

[23] Walton pleaded no contest to a misdemeanor weapons charge from the March 2019 incident on August 19, 2019, and he received six months of probation and was required to turn in all of his firearms as well as undergo anger management and driving courses.
