Baker Mayfield was caught popping a ZYN on Monday Night Football

Many things are needed on an NFL sideline to ensure players are ready to play…water, medical tents, video trays – and a container of ZYNs?!?

Well, at least that was the case during the Tampa Bay Buccaneers game against the Baltimore Ravens on “Monday Night Football”… because Baker Mayfield was seen taking his nicotine fix on the bench.

ESPN cameras caught Mayfield popping one of the popular pouches — touted as an alternative to tobacco products — just before the second half.

While it's hard to say whether the 29-year-old is an upper-class or lower-class guy (i.e. where the quarterback put him in his mouth) … the enthusiasm didn't give Mayfield the opportunity to mount a miracle comeback against Lamar Jackson and the Ravens – lost by a final score of 41-31.

At the end of the game, Mayfield at least put up respectable numbers… going 31-45 for 370 yards, three touchdowns and two interceptions.

They are now 4-3 this season and the team has suffered more than just one loss on the field – as both were star wide receivers Mike Evans And Chris Godwin went down with injuries… The latter is the end of the season.
