Bills receiver Stefon Diggs stayed on the field to watch Chiefs' championship ceremony until his coach pulled him off

• Stefon Diggs refused to leave the field after his team's AFC Championship loss Sunday night.
• The Bills WR looked on from across the field as the Chiefs celebrated earning their second-consecutive trip to the Super Bowl.
• He didn't leave until Buffalo head coach Sean McDermott came to pull him away.

Kansas City brimmed with joy Sunday night as the Chiefs locked up their second-consecutive trip to the Super Bowl.

But not every spectator inside Arrowhead Stadium was filled with glee.

Stefon Diggs watched Patrick Mahomes and company celebrate after their Kansas City squad dismantled his Bills 38-24 in the AFC Championship game. As the rest of his Buffalo teammates packed up their things and headed off to the showers, the mega-watt wide receiver stayed out on the gridiron and looked on as the Chiefs' victory ceremony and Lamar Hunt Trophy presentation unfolded downfield.

Diggs was presumably attempting to sit in the brutal feeling of falling short after coming as close as he ever has to his first-ever Super Bowl appearance. He refused to leave the field until Bills head coach Sean McDermott came back out to get him.

Though Diggs did not address the media after the game, McDermott explained after the game that his top receiver's post-game actions support the fact that "he's a heck of a competitor."

"It stinks to get this far," McDermott added. "Sometimes the farther you go, the harder it is to lose. It's a learning experience for us as an organization and we got to get back to work here."
