Houli missed four weeks for throwing his arm back without looking and knocking out lamb.
Seems like this incident should be similar, was in play but imo far worse. So 4 weeks min. Andrews being in the air and falling limp is just so so dangerous.
Edit; if memory serves Solomon got 6 weeks for his elbow on Ling, that’s probably the most like for like example I can think of.
Solomon was the first one that came to mind for me too. Although, watching it again now, Solomon's probably was a bit worse. I think he got 8 weeks.
