Baltimore Ravens quarterback Joe Flacco took the latest sports craze to another level, performing the mannequin challenge in-game.
The Ravens scored 25 unanswered points to beat the Cleveland Browns 28-7 and maintain top spot in the AFC North, ahead of rivals Pittsburgh Steelers.
The 'mannequin challenge', which involves teams freezing in life-like poses, has gone viral in recent weeks with the Pittsburgh Steelers, Dallas Cowboys and New York Giants all getting involved in the action with locker room and post-game videos.
However, Flacco took it onto the pitch. Following his four-yard touchdown pass to tight end Darren Waller, Flacco performed his usual, clenched-fist celebration.
He then held it for a period, as the home crowd roared around him. Flacco went on to throw for two more touchdown scores, condemning Cleveland to their tenth consecutive loss this season.
The mannequin challenge has not been limited to NFL, with WWE, the Barbarians rugby team, and Borussia Dortmund also participating.
