Team A downs a scrimmage kick at the 1 yard line. However, the team A play that downs the ball is standing in the endzone. 1st and 10 at the 1 or 1st and 10 at the 20?
Similar scenario! Team A's scrimmage kick bounces at the 1 and crosses the goal line in the air. Team A player catches the ball before it hits in the endzone standing at the 1 yard line. Touchback? Down at the 1 yard line?
