Touchdowns

In Winnipeg-Toronto Game today, Winnipeg up 14-3. Avery gets the ball at 25 yard line and runs to 1 yard line and jumps into endzone. He throws the ball while in the air unto the ground and then lands in endzone without the ball. Is that not a fumble. What is ruling on that?.

Did he break the plain of the goalline before throwing the ball? If he did he can throw it at anytime after, even if he is in the air.

I think it is ruled a touchdown yet because he had control of the ball when he crossed the goalline plain.

He was well past the plane of the endzone when he dropped the ball
