Jazz dude with the hand in the back, probably a foul, but a little soft But the shouldnt have been granted the challenge
To initiate a Challenge, the challenging team must take the following steps in sequence: (1)The challenging team must call a legal timeout immediately after the call in question (unless a mandatory timeout or timeout called by the opposing team is already underway); For purposes of this rule only, “immediately” shall mean that a timeout is called prior to the ball being given to the thrower-in, the ball being given to the free throw shooter, or the ball being tossed on a jump ball, whichever is applicable (unless a mandatory timeout or timeout called by the opposing team is already underway).
