The NFLPA said the behavior by an NFL official Sunday was "unacceptable" after line judge Jeff Seeman appeared to yell expletives toward Arizona Cardinals tight end Trey McBride during Sunday's game against the New York Giants. The interaction happened in the fourth quarter after a third-and-3 play on which McBride was arguing for pass interference. It's unclear what McBride said to the official, although CBS sideline reporter Aditi Kinkhabwala posted on social media that she was standing right next to the interaction and never heard him curse. Broadcast cameras appeared to show Seeman shout expletives toward McBride. The Cardinals lost 36-24 to the Giants, a result sealed with a pick six on the final play. NFLPA executive director JC Tretter, in a post on X, expressed his frustration with Seeman's behavior. "This kind of behavior from an official towards a player is unacceptable," Tretter wrote. "Players are consistently held accountable when the roles are reversed. We expect the NFL to hold officials to the same standard." An NFL spokesperson said, "We are looking into the matter." The Athletic has reached out to the NFL Referees Association for comment. This story will be updated if the association responds. Kinkhabwala wrote that the disagreement between McBride and Seeman began with the Cardinals tight end saying "please," while arguing for a pass interference flag. "He was heated for sure, but I never heard a curse from him," Kinkhabwala wrote. "The harshest he got was, 'You're ruining the game.'" Also on Sunday, in Minnesota, referee Adrian Hill fell after colliding with Vikings linebacker Eric Wilson. It appeared to be an accident, and Wilson offered to help him up, but Hill got up on his own and began to yell at Wilson. Another official came in to break the two up. The heated reactions from officials came on a day when New England Patriots coach Mike Vrabel was penalized for unsportsmanlike conduct, a rare call to be made against a coach. During a Patriots game against the Buffalo Bills, Vrabel used profanity to argue his case against a defensive holding call made on Patriots cornerback Marcus Jones, which prompted the flag. After the game, Vrabel stood by his language. "I told them that it was a terrible - I'm not going to say - effing call," Vrabel said after the game, which New England won 29-26. "I've said that 87 times since I've been a head coach. There was nothing derogatory. You know, you'd have to ask (the referee). I think he was a little sensitive." Referee Bill Vinovich, speaking to a pool reporter, said Vrabel was assessed the penalty because he was "out of the box, came up to the official and said, 'That was a f-ing horrible call.'" When asked if any warning was given, Vinovich said: "I don't know how you're going to give a warning. It's not something that is going to happen twice. When you use language like that, it's pretty much a given."
