Two? Changes of Possession

[ddn]

On fourth down and 10 with the game clock running, B30 intercepts A10’s pass and then fumbles the ball on the return, where it is recovered by Team A.

I had "1st and 10 for A and clock starts on the snap" based on 3.4.3.d since a change of possession occurred. According to the computer grading me, I'm wrong....


3.4.3 SITUATION D:

With third and 10:

(a) A1 fumbles the ball and B recovers, or
(b) A1's pass is intercepted by B. When will the clock be restarted?

RULING: Since a change of possession has occurred in both (a) and (b) and B is awarded a new series of downs, the clock will start on the snap.

Rule: 2-34-3

ART. 3 . . . A change of possession occurs when the opponent gains player possession during the down.
