Bill Belichick and the New England Patriots wound up on the losing end of a back-and-forth battle with the Minnesota Vikings on Thursday night.
Belichick clearly didn't take the loss well.
The legendary head coach, in his 23rd season with the Patriots, had no interest in shaking hands with Vikings players or coaches following the 33-26 defeat.
In fact, video has emerged of Belichick walking past Vikings wide receiver Adam Thielen on the field when Thielen tried to shake his hand. No surprise, the clip is going viral on social media.
It seems unlikely that Belichick has any personal animosity toward Thielen, who is not regarded as a particularly polarizing player.
But the Patriots' loss included a couple controversial moments that may have upset Belichick. Most notably, tight end Hunter Henry had what was initially called a touchdown on the field overturned by replay, even though there's still debate as to whether or not the ball actually touched the turf.
Belichick, who leads all NFL head coaches with six Super Bowl rings, showed his displeasure with the call after the game, although the savvy veteran avoided criticizing the officials and drawing a fine.
Belichick wasn't the only member of the Patriots whose frustration was evident Thursday. Quarterback Mac Jones spiked his helmet onto the turf following the final plays.
The Thanksgiving loss dropped the Patriots to 6-5 on the season and out of the AFC playoff picture, although they could reclaim the No. 7 spot if the New York Jets lose to the Chicago Bears on Sunday.
