NFL owners approved a rule change that will move the PAT from the 10-yard-line to the 15-year-line.
The extra point rule for 2015 just changed. Snap for kick from the 15-yard line, 2-pt try stays at 2-yard line and defense can return.

Additionally on PAT attempts, if the defense returns a blocked extra point or failed two-point try for a touchdown, they will be awarded two points. Under the previous rule the ball was dead on a failed try.
