It happened, once, then again and after that it just seemed like a running gag between players.
In three games over the weekend (that we can find), top-tier NRL players were referencing Fortnite in their post-try celebrations.
It started off with Sharks player Josh Dugan, before Roosters player (and Dugan’s friend) Blake Fergusson pulled it out. It was then up to two Warriors players to show the gaming world how it’s done. All four of these players referenced Fortnite’s bandaging animation in their celebration.
