The tackle that injured Tampa Bay Buccaneers wide receiver Chris Godwin on Monday night is reportedly being investigated by the NFL to determine whether it contains elements of the hip-drop takedown that the NFL banned from the game in March had.

The tackle occurred in the final minute of Monday night’s game between the Buccaneers and the Baltimore Ravens, which the Ravens won 41-31. Ravens linebacker Roquan Smith and another Ravens defender ran toward Godwin, who was trying to get a first down, and it was Smith who ultimately dropped Godwin to the ground.

It was clear immediately after the play that Godwin was in great pain. He was eventually carted off and head coach Todd Bowles said after the game that Godwin likely had an ankle dislocation. He will reportedly undergo surgery this week and miss the rest of the season.

While the tackle was not identified as a hip drop on the field, ESPN’s Adam Schefter said the tackle appeared to have “all the elements” of a hip drop tackle. Here’s the definition of a hip-drop tackle, straight from the NFL’s Football Operations website.

Had it been identified on the field as a hip-drop tackle, the Ravens would have received a 15-yard penalty, the Bucs would have automatically received a first down, and Smith would have been automatically fined $16,883 (the same as with horse harnesses, blindside blocks, etc.). Smith will still be fined if the NFL finds he made a hip-drop tackle on Godwin.
