What determines a sack?

They kept saying TJ didn't record a sack, but I distinctly remember him burying Fields on a fake. Is it because he never got into a passing position that they just called it a tackle for loss?

QBs always pull a fake handoff and roll out for a pass completion.

 

I was wondering this.

It seems a sack only officially counts within the pocket or “without clear intent”, or if the QB goes out of bounds behind the los.

 

He should have had the record against Tyler Huntley and the Ravens. The Ravens were clearly in a passing situation when Huntley bobbled the low snap and was tackled for a loss by TJ.

 

If it’s the play I am thinking of, he did bury Fields, but he had handed the ball off.

He handed off the ball before he was hit. It was such a quick play I thought it was a clean sack
