Athletic Bilbao scored twice in the final minutes for a 2-2 draw that dealt a serious blow to Levante's hopes of avoiding relegation from the Spanish league on Sunday.
Levante was set to provisionally escape last place after going ahead 2-0 with a goal by Victor Casadesus and an own goal by Xabier Etxeita.
But Inaki Williams set up strikes for Markel Susaeta in the 88th and Mikel San Jose in stoppage time to ensure the hosts stayed bottom with only three matches left.

"It's impossible to explain," Levante forward Jose Morales said. "Eighty-eight minutes working to earn three points that would have kept us in the fight, and I just don't know what to say now."
Bilbao remained in fifth place -- a Europa League spot.
