1st and 10 for A on their 30. QB drops back to pass and is facemasked (15 yd) at the 23. QB keeps running and completes a pass to the 50 where the receiver is tackled at the B45.

Would this facemask, if accepted, be enforced from the previous spot (since it occurred during a loose ball play) or would it be enforced from the end of the run at the B45?

I'm thinking previous spot, but I'm doubting myself.

Thanks!
