NSW five-eighth Jarome Luai and Queensland fullback Reece Walsh have both been sent off for head-butting one another during a melee in the final minute of the Maroons' 32-6 State of Origin II victory.

Blues winger Josh Addo-Carr found himself sin-binned for appearing to throw a punch in the fracas, which broke out after the hosts repelled a late NSW attack.
