Referee Jerome Garces was left with no choice.
Sonny Bill Williams was sent off after 24 minutes of the
Second Test between New Zealand and the Lions after a quite gruesome head-hit on Anthony Watson.
With the game tied 3-3 in squalid conditions, Williams crunched into Watson's temple with a stiff shoulder.
Each replay of the incident made it look worse and Garces sent Williams on his way. He is the first All Blacks player to get a red card since Colin Meads in 1967.

Watson went off for a Head Injury Assessment but was deemed safe to play on.
There was a strong reaction to the hit online:
