ESL has officially locked in the rosters for all 32 teams heading to the IEM Cologne Major 2026, with most squads choosing to bring either a coach, a benched player, or an academy prospect as their listed substitute. The lineup confirmation sets the stage for the first Counter-Strike Major of the year, though a few unresolved stand-in situations still hang over the event.

For most of the field, the substitute slot is more of a formality than a plan. A handful of teams, however, are walking into Cologne with stand-ins who will play from the first map, not the bench, which meaningfully changes the competitive picture going in.

Teams Playing With Stand-Ins From Day One

Falcons will field Finn “karrigan” Andersen at the Major, with the veteran in-game leader slotting in rather than sitting as a backup option. It is the kind of situation where the “substitute” label on paper does not match the reality on the server.

MOUZ are in a similar position. Adrian “xelex” Vincze is stepping in for Jimi “Jimpphat” Salo, and the event will be Ludvig “Brollan” Brolin’s last with the team. That is a significant moment for one of the more consistent young cores in Counter-Strike over the past couple of years, and it will be playing out under the brightest lights the game has to offer.

Gaimin Gladiators are rolling with Fernando “fer” Alvarenga as part of their starting five rather than as a reserve. The Brazilian veteran’s inclusion gives the roster a different competitive identity than the one listed on the official sheet.

The BetBoom Situation Remains Unresolved

The biggest question mark hanging over the locked rosters is BetBoom. The organisation has not confirmed who will actually take the server for them in Cologne, telling HLTV that they cannot share information yet and need to wait for official announcements.

BetBoom qualified for the Major using stand-ins Aleksandr “zorte” Zagodyrenko and Timur “FL4MUS” Marev. Zorte then joined the team properly, replacing Artem “ArtFr0st” Kharitonov, but the picture has not fully settled since. Daniil “d1Ledez” Kustov’s availability is clouded by visa issues, while FL4MUS’s loan from Virtus.pro ended after the qualifier run concluded. The listed roster on the official sheet names FL4MUS and d1Ledez, but neither is a certainty to play.

The Picture Going Into Cologne

With rosters locked, the storylines heading into the Cathedral of Counter-Strike are starting to crystallise. Brollan’s farewell run with MOUZ, Falcons relying on karrigan’s in-game leadership, and BetBoom’s scramble to confirm a usable five are the situations most likely to shape the early narrative of the event. The rest of the field looks largely as expected, which puts more pressure on the teams dealing with disruption to prove they can still make a deep run.

MOUZ have confirmed a major shake-up of their CS2 roster, signing Justinas “jL” Lekavicius on a short-term loan from Natus Vincere and promoting MOUZ NXT prospect Adrian “xelex” Vincze to the main team. Ludvig “Brollan” Brolin and Jimi “Jimpphat” Salo have both been benched, while Dorian “xertioN” Berman steps up as the new in-game leader. The catch: Major Supplemental Rulebook restrictions mean jL cannot debut at IEM Cologne, so Brollan returns for that event only.

We are making the following roster changes effective immediately. Our roster will be as follows for the next three tournaments:

Astana and Shanghai:

• xelex
• Spinx
• torzsi
• xertioN (IGL)
• jL (On loan from NAVI)

Cologne Major:

• xelex
• Spinx
• torzsi
• Brollan… pic.twitter.com/tHG7odkNmz

— MOUZ (@mousesports) April 18, 2026

The announcement, made on 19 April 2026, ends weeks of speculation about how MOUZ would respond to a steep dip in form after more than a year as one of the most consistent teams in Counter-Strike.

The New MOUZ Roster Explained

The changes take effect immediately, but MOUZ will run two slightly different lineups across the next three tournaments because of Major rules. jL slots in for the Asian swing at PGL Astana 2026 and CS Asia Championships, while Brollan returns as a one-event substitute at IEM Cologne before officially leaving the organisation.

xelex, xertioN, torzsi and Spinx are the four constants across both rosters. xertioN takes over the in-game leader role full-time, with xelex stepping into the pack opener slot that xertioN previously occupied.

Dennis “sycrone” Nielsen remains in the coaching seat across all three events.

Why jL Cannot Play The Cologne Major

The split-roster situation comes down to the Major Supplemental Rulebook. Teams are locked into the lineup that was listed on the invite VRS from 6 April, and they are only permitted one change through a substitute. MOUZ have used that substitute slot to bring Brollan back for Cologne, which means jL has to sit the event out despite already being a signed player.

MOUZ explained the unusual timing as a deliberate choice to give the new lineup a head start rather than wait for a cleaner window after the Major. The organisation said confidence in the previous roster’s ability to bounce back had run out, and that prioritising preparation for the next competitive cycle outweighed keeping the existing five intact for one more tournament.

Brollan And Jimpphat’s Exit

The decision to move on from Brollan is the more delicate of the two. He was the player who took on in-game leadership duties after Kamil “siuhy” Szkaradek was removed in early 2025, and that transition kicked off the run that saw MOUZ reach at least the semi-finals at 13 of 15 events between early 2025 and early 2026.

That stretch ended sharply. The team has missed the top four at three consecutive events, capped by a last-place finish at BLAST Open Rotterdam last month.

This decision is not fair to him on a personal level. But leadership sometimes means accepting that fairness and necessity are not always the same thing.

That line came from sycrone in his statement on the changes, acknowledging Brollan’s role in the team’s previous success while explaining the call to bench him. Brollan will leave the organisation entirely after the Cologne Major, and his replacement has not yet been announced. Jimpphat has already been removed from the active roster.

xelex’s Promotion From MOUZ NXT

xelex’s call-up continues a now-familiar pattern at MOUZ, where the academy team has steadily fed the main roster. xertioN and torzsi both came through the same pipeline, and xelex now joins them after a year and a half in MOUZ NXT.

The Hungarian rifler put up a 1.21 average rating across 154 maps in 2026, a workload that landed him in the top 15 of HLTV’s Prospects series as of last month. MOUZ’s CBDO Jan Dominicus framed the promotion as consistent with the organisation’s preference for in-house development, calling xelex a player aligned with that philosophy.

jL’s Return To Tier-One CS

For jL, the loan deal is his first appearance on a professional roster since he stepped down from Natus Vincere in July last year to take time away from the game. The trial spans only the Asian swing for now, with Astana opening on 7 May.

Dominicus said the team is looking for jL to bring initiative in tough situations and to lift the squad’s communication, two areas the organisation appears to feel were lacking. Whether that short window is enough to convert the loan into something permanent will likely depend on how the new five gel before the post-Major reset.

What Comes After Cologne

The Cologne Major is the closing chapter for the current era of MOUZ as much as it is the next event on the calendar. Brollan walks away, jL’s loan ends without a guaranteed extension, and MOUZ still need to lock in a fifth player for whatever the next competitive cycle looks like. The Astana and Asia Championships campaigns will effectively serve as the audition window for the version of MOUZ that follows.
