It's a Fumble, Whoaaa Nelly!!

[ABoselli]

On 3rd and 11 from the A 3 yd line, A1 takes a pitch and is immediately hit in his own endzone by B1 who grasps and pulls A1's facemask while tackling him. Before A1 goes down, he fumbles the ball into the field of play and it goes out of bounds at A's 3. A1 then punches B1 and calls him a bad word.

Where's the ball next and what down is it (assuming the A captain isn't a complete nitwit) ?
