Nico Williams is set to be sidelined for 6 to 8 weeks due to persistent pubalgia as he undergoes a new treatment approach following previous therapy with Athletic Club that failed to bring improvement. The 23-year-old Spanish winger suffered a relapse during Athletic’s recent El Derbi Vasco match and will now pursue a different conservative treatment plan in hopes of avoiding surgery.

The Pubalgia Issue

The groin complaint has dogged Williams since late last season, with the club’s medical team weighing options from conservative care to surgery. The goal of the treatment is to avoid surgery, which would be the alternative if this therapy proves ineffective. Athletic Club’s medical staff determined that a more intensive treatment plan would be necessary after the initial conservative approach yielded limited results.

Athletic Bilbao director of football Mikel González confirmed that pubalgia is rarely operated on because it can have negative consequences such as loss of speed or acceleration, with recovery from such procedures taking between three and six months. This decision prioritizes maintaining Williams’ explosive attributes crucial to his playing style.

Impact on Athletic and Spain

The absence arrives at a delicate moment for Athletic Club, who currently sit 11th in La Liga, closer to the relegation zone than European spots. Having played 22 matches this season, Nico has scored four goals and provided five assists. The club will rely on alternatives like Álex Berenguer and Robert Navarro during his extended time on the sidelines.

With the persistent pelvic injury affecting him, Nico Williams’ chances of taking part in the 2026 World Cup, scheduled in the United States, Mexico, and Canada, are now in serious jeopardy. This development creates significant concerns both for the Spanish national team and the player’s future career trajectory.

Medical Strategy and Recovery Plan

The first conservative approach implemented by the club did not improve the injury, which has limited his performance and playing time. Athletic Club has now opted for a more comprehensive treatment regimen that combines ongoing physiotherapy with targeted strengthening exercises specifically designed to address pubalgia complications.

The current plan combines ongoing treatment with competition, with the possibility of a few weeks’ rest for targeted strengthening therapy if needed. This balanced approach attempts to maintain Williams’ fitness while allowing adequate recovery time for the chronic condition.

Williams’ Playing Style and the Injury Challenge

Pubalgia directly impacts Williams’ game, as his style revolves around pace, sharp directional changes, and explosive take-ons. Williams’ game leans on pace and dribbling, so a full recovery is crucial. The condition affects acceleration and stride length, precisely the qualities that make him one of La Liga’s most feared attacking talents.

Athletic’s Search for Alternatives

With Williams sidelined, Athletic boss Ernesto Valverde has rotated options to maintain squad balance. To cover Nico’s absence, Valverde has relied on players like Berenguer and Robert Navarro, who will once again play prominent roles in the coming weeks. Both players have emerged as joint top scorers for Athletic on four goals each this season.

Return Timeline and World Cup Implications

If the conservative treatment proves successful, Williams could potentially return around mid-March, which would theoretically provide time before Spain’s Finalissima match against Argentina.

However, He could make a return for Spain’s Finalissima showdown against Argentina at the end of March, although the likelihood is that he will not be risked.
