On the 29th of May (KST), Griffin announced that they've promoted trainee, Choi "Doran" Hyeon-joon to their active roster. Doran was known for his exceptional performance on Kled during his amateur days. This top laner, performed in the 2018 KeSPA Cup as a member of KeG and led the team to victory against Hanwha Life Esports.

"I'm happy to join the team for this LCK Summer Split. I'll try my best to become a player that can devote to the team for the LCK title." said Doran.

Meanwhile, Griffin signed jungler, Seo "Kanavi" Jin-hyeok, and support, Jeong "Kabbie" Sang-hyeon for the 2019 LCK Spring Split to form a 7-man roster. However, with their starting jungler and support, Tarzan-Lehends delivering solid performance, the new players weren't given the chance to perform in official matches. We'll have to wait and see whether their new substitute top laner, Doran would get some time on stage.
