Baker Mayfield seen using nicotine pouch during Monday Night Football game, receives warning letter from NFL.

Baker Mayfield, quarterback for the Tampa Bay Buccaneers, was seen using Zyn, a nicotine pouch, during a Monday Night Football game. Although nicotine is prohibited on the sidelines, he will not face a fine or suspension but will receive a warning letter from the NFL reminding him of the rules. Zyn, gaining popularity since 2014, is not explicitly covered under the league’s substance policies, prompting the league's measured response.
