Dolphins RB Duke Johnson appears to take a shot at Baker Mayfield, Browns on Twitter

He’s ruthless.

Miami Dolphins running back Duke Johnson is preparing to hit the free agent market on Wednesday at 4 p.m. ET at the start of the new league year, but that hasn’t stopped him from staying up on all of the news around the league.

On Tuesday, Cleveland Browns quarterback Baker Mayfield posted a message on Twitter thanking their fans with uncertainty in his future as rumors swirl about their quarterback situation.

Duke Johnson took that opportunity to take a solid jab at his former team and quarterback with a tweet of his own depicting a train that has gone off the rails.

Mayfield and Johnson have some past discretion, as the quarterback seemed to take some offense to the running back asking for a trade in 2018, Mayfield’s rookie season.

“You’re either on this train or you’re not, it’s moving,” the Mayfield said. “You can get out of the way or you can join us.”

Johnson may not be with the Dolphins for much longer, but this level of trolling has probably earned him some lifelong fans.
