Athletic Bilbao will miss the duo of Nico Williams and Inaki Williams in the second leg of their Europa League semi-final against Manchester United on Thursday.
The brothers were not selected for the travelling squad for the match.
The LaLiga club mentioned injury as the cause of their absence
Nico and Inaki kicked off the first leg at San Mames, where United secured a 3-0 victory, putting them one step closer to the final.
They will not be available, though, as Athletic pursue an improbable comeback.
Nico has seen limited use in the league recently, as manager Ernesto Valverde is trying to keep him fresh for European competition.
However, he did not play at all against Real Sociedad over the weekend and is unavailable on Thursday night.
Although Inaki participated in the match, he was substituted for Alvaro Djalo approximately one hour into the scoreless draw.
Oihan Sancet, the top scorer, was sidelined due to injury for the first leg and did not recuperate in time to participate at Old Trafford. Dani Vivian will also be unavailable due to a suspension resulting from his red card in the first leg.
