The NFL suspended Denver Broncos linebacker Dre Greenlaw for one game on Monday after he chased down and berated an official after their wild win over the New York Giants on Sunday.

Greenlaw, the league said, chased down referee Brad Allen and "verbally threatened him" as he tried to leave the field following the team's 33-32 win over the Giants. Greenlaw was spotted running after Allen shortly after Wil Lutz made the game-winning kick and the rest of the team was celebrating. Allen actually threw a flag on Greenlaw, but the game was already over at the time. 

It's unclear what Greenlaw was mad about specifically or what he actually said to Allen in the moment. Greenlaw, according to the NFL Network's Ian Rapoport, is expected to appeal the suspension.

Greenlaw had six total tackles in the Broncos' win, which moved them to 5-2 on the season. The 28-year-old is in his first season with the Broncos. He signed a three-year, $31.5 million deal with the team this past offseason.

The Broncos rallied back and scored all 33 of their points on Sunday in the fourth quarter to pull off the stunning win. Their 33 points is the most points scored in the fourth quarter by any team that was shut out in the previous three in NFL history. Quarterback Bo Nix is the first player in league history to record multiple touchdown passes and multiple touchdown runs in the same game, too. His second rushing touchdown, an 18-yard burst late in the fourth quarter, gave the Broncos their first lead of the game. 

The Broncos, who have now won four straight, will host the Cowboys next on Sunday. If Greenlaw's suspension is upheld, he'll be eligible to return for their Nov. 2 matchup against the Houston Texans.
