Take that, Baker!

49ers defensive end Nick Bosa pretended to plant an imaginary flag on the field Monday night after sacking Baker Mayfield, mimicking the Browns quarterback who planted a University of Oklahoma flag on Ohio State’s field in 2017 after Mayfield’s Sooners beat Bosa’s Buckeyes.

Mayfield drew a ton of ire for the flag-planting incident on the way to becoming one of the NFL’s most polarizing players.

This also wasn’t the first time Mayfield has been imitated: An Iowa State player planted his school’s flag in Oklahoma after upsetting the Sooners later that season.

Bosa had one sack and three tackles through halftime on Monday, while Mayfield was just 7-of-16 for 80 yards.
