3-3-1n. initiate malicious contact on offense or defense;
In (n), ... if on offense, the player is ejected and declared out, unless he has already scored.
It is always hazardous to port one rule to cover an unrelated play. That said, I'd agree, but not admit that I used the MC exception.
In the OP side note, it says that R3 did a much safer thing, diving over F2, rather than collide full speed with F2. You have to give R3 consideration for avoiding the contact/collision...doesn't merit a stiffer penalty. Of course, that consideration is moot if there is an actual rule to apply. But in this case, none seem to apply.
