Yeon, CoreJJ reportedly set to join Cloud9 in 2027

Sean “Yeon” Sung and Jo “CoreJJ” Yong-in are reportedly set to leave Team Liquid and join Cloud9 for the 2027 LCS season. The reports were published Thursday, Nov. 12. The duo have played together in the bot lane since 2023 and could continue that partnership with Cloud9.

If the signings are completed, Yeon and CoreJJ are expected to replace Edward “Tactical” Ra and Philippe “Vulcan” Laflamme. Tactical has permission to explore other opportunities despite having a contract with Cloud9 through November 2028. Vulcan is signed through 2029, so his departure would require an agreement between the organizations. Shopify Rebellion is reportedly interested in both players. Cloud9 is expected to retain Robert “Blaber” Huang and Lee “Loki” Sang-min for 2027.

The reported roster changes follow a titleless 2026 season for Cloud9. The team finished third in both the Spring and Summer Splits. Cloud9 also lost the Lock-In final to LYON 3-1 and the Americas Cup final to FURIA 3-0.

Cloud9 returned to the World Championship after a two-year absence. The team lost to Karmine Corp 3-2 in the Play-In Stage before falling to FURIA 3-1 in the elimination series.

Yeon joined Team Liquid Academy in December 2020 after competing with 100 Thieves Next. He remained on Liquid’s developmental roster through 2022 and became the team’s starting ADC before the 2023 season. He has held that position for four consecutive LCS seasons.

Team Liquid won the 2024 Spring title after defeating FlyQuest 3-1 in the final. The team reached the championship series again later that year but finished second. In 2026, Liquid lost the Spring final to LYON 3-0 before defeating the same opponent 3-1 in the Summer final. Liquid then earned the region’s first seed at Worlds, where it was eliminated by LOS 2-1 in the Swiss Stage.

CoreJJ joined Team Liquid in November 2018 after starting his career as an ADC and switching to support with Samsung Galaxy. He reached the 2016 World Championship final and won the 2017 title with Samsung Galaxy, defeating SK Telecom T1 3-0.

CoreJJ helped Team Liquid win the 2019 Spring and Summer titles and received the Spring 2019 MVP award. He also won the Summer 2020 MVP award, the 2021 and 2022 Lock-In tournaments, the 2024 Spring title, an LTA championship in 2025 and the 2026 Summer title.

LYON reportedly considered signing CoreJJ for 2027, but he is expected to choose Cloud9. His departure would end his eight-year tenure with Team Liquid. Cloud9 has not officially announced changes to its 2027 bot lane.
