FUR suspend Tatu for one CBLOL match, KT promote FenRir from KT Challengers
TL;DR
FUR jungler Tatu is suspended for one CBLOL match after communicating with a person outside the stage during Champion Selection. KT also added bot laner FenRir from sister team KT Challengers on July 29.
FUR will be without Tatu for one CBLOL match after the jungler was suspended for communicating with a person outside the stage during Champion Selection. That disciplinary move was the clearest immediate change from July 29, because it takes a starter out of FUR's lineup for a confirmed match.
KT's roster move was a direct addition. The organization brought in bot laner FenRir from sister team KT Challengers, giving the main roster a confirmed new player from within its own system.
The two updates came from different regions and under very different circumstances. FUR's change was a suspension tied to a rules violation during draft proceedings, while KT's was a standard roster addition involving FenRir's move over from KT Challengers.
Tatu's one-match absence is the only confirmed competitive consequence listed in the July 29 updates. FenRir's transfer is confirmed as a move from KT Challengers to KT, and the teams named in the day's changes were FUR and KT.
