LCS Transfer: Reports Say CoreJJ and Yeon Will Both Join Cloud9

CoreJJ and Yeon have long been part of Team Liquid’s core League of Legends roster, but new reports say the duo are moving to Cloud9 for the 2027 LCS season. Here’s everything fans should know.

CoreJJ and Yeon Transfer from Team Liquid to Cloud9

On November 12, 2026, reports from Sheep Esports emerged with new information about the 2027 LCS season. Sean “Yeon” Sung and Jo “CoreJJ” Yong-in, both on Team Liquid‘s starting roster, have reportedly reached a verbal agreement and will transfer to Cloud9 for the 2027 season.

This is particularly significant as the pair play together as a botlane duo. With existing chemistry on ADC and Support, Cloud9 would be securing a package deal that already has a synced style.

The move is also notable as both players have spent over six years with Team Liquid, becoming familiar faces to League esports fans in the Americas. CoreJJ has been on the lineup for eight years, more than half its League of Legends competitive lifespan. Yeon, meanwhile, entered tier 1 through Team Liquid’s Academy roster four years ago.

What’s Cloud9’s LCS 2027 Roster?

Once Yeon and CoreJJ complete the transfer, Cloud9’s starting roster in 2027 would reportedly include:

• Robert “Blaber” Huang (Jungle)
• Lee “Loki” Sang-min (Mid)
• Sean “Yeon” Sung (Bot)
• Jo “CoreJJ” Yong-In (Support)

In this case, there would still be one empty slot left for a toplaner.

What Does This Mean for the LCS 2027 Season?

LCS teams have long experienced struggle on the international stage, where LCK and LPL orgs tend to dominate the competition. Esports fans saw some shakeups this year that put the different regions at closer standings than expected: G2 knocked T1 out of MSI, and LYON notably made it into the Worlds 2026 playoffs. However, Team Liquid and Cloud9 were not as lucky.

Team Liquid had a strong finish to LCS 2026, taking first prize in the Summer Split. However, after qualifying to Worlds, the org faced elimination in the Group Stage. Cloud9 had a weaker conclusion, ending their run at the bottom of the ladder at 19th place. Both teams are likely looking to increase their competitiveness for next year’s circuit.
