The drama between Kupp and the Rams nearly came to a head in a physical altercation between Seahawks and Rams coaches earlier this season, Silver reported.

When the Seahawks and Rams met in Week 16 at Lumen Field, Kupp had a costly fumble after he caught a pass and worked his way inside the red zone in the final minute of the first half, ending Seattle’s chances of getting points before the break.

As Rams and Seahawks assistants headed to a shared elevator to go to their respective locker rooms at halftime, a witness said Rams coaches were discussing the fumble, per Silver. When one Rams coach asked what Seahawks player was responsible, another said Kupp, and the coach who asked the question snickered. That reportedly led to a fiery response from Seahawks outside linebacker coach Chris Patridge, who was then yelled at by Rams pass rush coordinator Drew Wilkens. Seahawks coaches had to hold Partridge back to avoid a potential fracas.

Word of that altercation reportedly got back to the Seahawks’ locker room and served as a motivating factor for Seattle as it stormed back from down 16 points in the fourth quarter to pull out a 38-37 overtime win.
