foul away from play

[linesman]

Can B legally grab A by the jersey? Or throw A to the ground away from the play? Go to 9-4-2b in the NFHS rule book. Also 9-2-3. just to add to the thread, it was a rather forcefull pull to the ground by B he definitley grasped the back of A's jersey..... the official flagged it for defensive holding .... I thought it should be Illegal personal contact if anything... just wanted to hear what others thought .... thanks!!
