According to a competitive League GCD update, Academy mid laner David "Insanity" Challe has been inserted into the starting lineup as a replacement. Although experienced mid laner Kim "Fenix" Jae-hun was also thought to be joining since his name also appeared in the database under the TSM brand, he and Lee "Ruby" Sol-min will be the team's newest players.
If Insanity joins TSM, he will be the group's first mid laner from the North American continent since 2014, when current CEO Andy "Reginald" Dinh was still a competitive player. His contract will end "upon TSM Summer LCS elimination," according to the database, therefore he will only be hired while the team is competing live. On June 1, 2023, the LCS will resume for the Summer Split, with TSM beginning their final split in North America by taking on Team Liquid and FlyQuest.
