RL Jerseys on Instagram did this earlier in the year which shows the deals.
Supposedly Broncos officials were in Japan last week signing a contract extension with Asics, so that's them sorted. I've seen a few people say Bulldogs are meant to be going to O'Neils next year, but that would mean either the club or Classic are breaking the extension
announced in 2022.
Not sure when Wests Tigers extended with Steeden. Originally the
deal was only for 3 seasons (2021, 2022, 2023), but would much prefer them to go to someone like Dynasty.
