On the 27th (KST), Jin Air Green Wings announced their 2019 LCK Spring Split roster through their social media account. They were seeking to rebuild their roster by releasing most of their key members; recently they set parts with Teddy, SoHwan, Justice, KaKAO, and coach Fly. 

This LCK team named Heo "Lindarang" Man-heung as their starting top laner. Formally playing for  Afreeca Freecs, ROX Tigers, Hanwha Life Esports, he has been gradually improving throughout his pro career. Jin Air also signed Lee "TaNa" Sang-wook for their sub top laner. Amateur LoL player, TaNa will be starting his first LCK career in Jin Air Green Wings. 

Kim "Malrang" Geun-seong will be filling in for their former jungler, UmTi. Debuting on 2017 in Ever8 Winners, Malrang led his team to the Challengers Korea title. He and his teammates also won the promotion match and made it to the LCK. However, after being relegated, he moved to the TCL and then he came back to Korea and joined Winners. Although he and his team failed to promote to the LCK, Jin Air signed him for his solid performance in Challengers Korea.

For the starting mid position, Lee "Grace" Chan-ju will once again perform. Joining the team on late 2017, he delivered consistent performance in the 2018 LCK Spring-Summer Split. Meanwhile, Choi "CheonGo" Hyeon-woo, who is famous for his Zed, has joined the team as well; he will be a substitute mid laner for Jin Air. 

Also, Lee "Stitch" Seung-ju has come back to the LCK for the starting ADC of Jin Air. After his 2-years in Samsung Galaxy, Stitch moved to LMS' G-Rex. After leading the team to Rift Rivals and Worlds, he decided to once again continue his career in Korea. For their sub ADC, former APK Prince player, Moon "Route" Geom-su has been chosen. 

Park "Nova" Chan-ho, who has performed for Jin Air last split, will team up with their new ADC, Stitch in bottom lane. Nova filled in for Jin Air's support position after Kwon "Wraith" Ji-min retired from the scene. Although his performance was shaky at first, he eventually managed to adjust and deliver solid performance in the LCK. 

In Spring-Summer regular split, Jin Air Green Wings finished 7th-8th and avoided going to the Promotion Match. With most of the LCK teams going through a rebuilding process, Jin Air seems to have also succeeded in signing some concrete players for their 2019 roster.
