Stat changes were posted on Yahoo this morning...makes sense that the NFL/Elias wanted to finish them before the holiday.
As for Fitzpatrick, this is a good reddit thread that discusses the play and contains several references as to why it was scored the way it was. This one in particular.
EXCEPTION: If the player recovers his own fumble, all yardage gained or lost shall be credited in the category initiating the action.
Example II: In the same situation as Example I, the receiver recovers his own fumble and advances to a point 45 yards in advance of the line of scrimmage before being tackled. Scoring: Play is listed as a 45-yard pass.
