Liverpool left-back Fabio Aurelio's season appears to be over after he was ruled out for at least three weeks with a torn abductor muscle.
Aurelio was injured against Chelsea in the Champions League semi-final, first leg 1-1 draw while his replacement John Arne Riise scored a late own goal.
"It usually takes a minimum of three weeks to recover," Reds boss Rafael Benitez told the club's website.
"So, it will be very difficult for Fabio to play again this season."
Brazilian Aurelio returned to action last September after rupturing his Achilles in April 2007.
He played his first competitive game of the season against Porto in the Champions League and has since made 28 more outings on the way to establishing himself as the Anfield side's first choice at left-back.
Benitez added: "It is very disappointing because Fabio has been doing a good job for the team."
