3 Jump Ball / Arrow Ques

[Stan]

#1 you kicked. Neither jumper may catch the ball before
the jump ball ends. It ends when it hits the floor, a
non-jumping player, backboard or basket. BTW, neither
player may touch th eball more than twice. (As I reread this I see I should mention if the ball hits the floor
without either jumper touching it you re-do the jump.)
Look in Rule 6.

Neither player may touch the ball twice? If they do is that a violation or a do over?

Thanks
