There was injury added to insult for Athletic Bilbao, with promising striker Inaki Williams injuring his right hamstring in its UEFA Europa League outing.

Bilbao was a 3-2 loser to Zilina in the first leg of its play-off, the Supercopa de Espana champion making nine changes to the starting XI that drew 1-1 with Barcelona at Camp Nou to end its trophy drought.

Preparing for its hosting of champion Barca in Primera Liga on Monday (AEST), Bilbao coach Ernesto Valverde will be without Williams - who was withdrawn just eight minutes after coming on as a second-half substitute in Zilina.

A Bilbao statement revealed the 21 year-old, who scored against Barcelona in the Copa del Rey final in May, was undergoing tests to determine the extent of the injury.
