After NAVI placed him on the bench in July 2025, jL filled in for MOUZ at 2 tournaments.

The available preparation time is a central part of jL’s account of the stand-in assignment. He said Vitality had not practiced much with him because of the Esports World Cup, but added that the group would train on the day of the interview and again before its first match. He described the planned work as an increase in training hours rather than as a completed period of team practice.

His comments separate individual confidence from the practical work of replacing mezii. jL said Vitality have five individually strong players and included himself in that assessment. At the same time, he did not claim that the short preparation had already produced a result; his stated task was to play and perform well after learning the team’s calls and the responsibilities attached to mezii’s position.

The tournament also gives a defined competitive consequence to the substitute role. Vitality must finish among the three highest-placed teams in its group to reach the playoffs in Portugal. jL’s first match with the team therefore comes in a group stage that directly determines whether the roster continues to the later portion of BLAST Open Porto.

jL outlines how he prepared for the Vitality stand-in role

jL said he had kept track of Vitality before joining the team for this event. In his description, that work included watching the roster’s Esports World Cup matches and reviewing its tactical book. He also said that he knew mezii’s functions, giving him a documented basis for the replacement assignment despite the limited joint training.

The player’s direct assessment was concise: “I know what I need to do.” That statement was tied to his knowledge of Vitality’s tactics and of mezii’s duties, not to a claim that the lineup had undergone extensive preparation. jL said the team would use the remaining time before the opener to practice.

This is not jL’s first period as a stand-in since leaving NAVI’s active lineup. He was moved to NAVI’s bench in July 2025 and subsequently played as a stand-in for MOUZ at two tournaments. In July of this year, his NAVI contract ended, leaving him available on the market before Vitality’s August announcement.

  • Documented preparation: jL watched Vitality’s Esports World Cup matches, studied the team’s tactical material and learned the duties associated with mezii.
  • Documented practice plan: jL said Vitality would train on the day of the interview and again before the first match after having little time to practice together.
  • Documented tournament requirement: the three best teams in each group qualify from the Denmark-based group stage to the playoffs in Porto.

The available chronology places the assignment after a sequence of roster and competition changes for jL. His move to NAVI’s bench occurred in July 2025. He later stood in for MOUZ at two tournaments, and his NAVI contract reached its end in July of this year. The Vitality announcement at the beginning of August followed that contract endpoint.

For BLAST Open Porto, the immediate reason for the change is specific: mezii is on parental leave. The evidence identifies jL as the player filling in for Vitality and identifies Inner Circle as the opponent for his first appearance. It does not provide a broader roster change beyond this tournament replacement.

The event structure gives the next steps a clear boundary. Group matches are held in Denmark, and only three teams per group proceed to Porto for the playoffs. That means the group phase, beginning with the Inner Circle match, is the stage in which Vitality can secure progression under the stated format.

Timeline and tournament facts

jL spoke before his first match as Vitality’s substitute at BLAST Open Porto. He said that he had spent time without official tournament competition because he had not joined a team. The report also places the end of his NAVI contract in July and notes that he subsequently filled in for MOUZ in 2 tournaments. His Vitality assignment is specifically a replacement for mezii during parental leave.

The report separates jL’s individual preparation from the limited time available to practice with Vitality. He said he had examined the team’s Esports World Cup preparation, watched every match, and learned the tactical system. He also said he knew mezii’s usual duties and the work required of him. Because Vitality had attended the Esports World Cup, jL had not been able to train extensively with the lineup; additional practice was planned before the first match.

The tournament information is reported independently of jL’s prior team history. Vitality’s group-stage opener is against Inner Circle on Thursday, and the initial stage will be held at the BLAST studio in Denmark. The 3 best teams from each group advance to playoffs in Porto, Portugal. The report also records jL’s assessment that the roster has 5 individually strong players, including himself.

jL enters BLAST Open Porto with limited practice time alongside Vitality but with preparation based on studying the team’s matches, tactics and mezii’s responsibilities. His first test is the group-stage match against Inner Circle in Denmark.

For Vitality, the substitute arrangement applies while mezii is on parental leave. The team’s route to the Porto playoffs is set by the group format: a place among the top three in its group is required to advance.
