BILL BELICHICK removed BOTH of his masks from his face Monday to scream at officials after a bad call … and it seems obvious a huge fine is coming his way.

The New England Patriots head coach arrived at Arrowhead Stadium in Kansas City wearing TWO masks … seemingly trying to send a message that he’s taking the NFL’s COVID rules seriously.

But, when the Patriots appeared to force a HUGE turnover late in the 2nd quarter — only to have the play waved off by officials — Belichick lost his damn mind.

Long story short … Pats defensive end Chase Winovich appeared to strip Mahomes of the ball during a big 3rd down play — with another Pats player catching the ball before it hit the ground.

It seemed like a solid turnover that would give the Pats the ball deep in Chiefs territory … a potential game-changer!

But, the refs ruled that Mahomes was “in the grasp” and blew the whistle dead BEFORE the turnover — meaning Chiefs kept possession.

Belichick went NUCLEAR — ripping down his two masks and unloading at the refs … breaking COVID protocol.

The NFL has been fining coaches for removing masks to yell — Raiders coach Jon Gruden was hit with a $100,000 fine for similar antics during Week 2.

Belichick is rich and can afford it — but the NFL is trying to send a message … STOP TEARING OFF YOUR MASKS!!!!

The Pats — who were forced to play without Cam Newton after he tested positive for COVID over the weekend — ultimately lost to the Chiefs in a 26 to 10 beatdown.
