Hmmm. Quite likely the case it'd break its arms with that mass. However, 
the rex has to hit with something, a something which most likely be its head.

Now, with all that mass impact being borne by the head it _seems_ like 
there'd be the potential for broken jaws, or fractures, or whatever.

Do any known rex skulls exhibit such injuries on the lower jaw?
