LONDON, Sept 17 (Reuters) - Liverpool left back John Arne Riise has been ruled out of his side's Champions League opener in Porto on Tuesday because of a groin injury.
The Norwegian injured himself on international duty last week and will not travel to Portugal, the club's website said on Monday. Midfielder Mohamed Sissoko will also miss the trip.
Better news for last year's runners-up is the return to fitness of Fabio Aurelio, who will be in Rafael Benitez's squad for the Group A clash.
Brazilian Aurelio has been out since April after rupturing his Achilles tendon against PSV Eindhoven in last season's Champions League quarter-final.
'Fabio is back which is good news for us,' manager Rafael Benitez said. 'He has worked hard to recover from his injury and could be a useful asset for us.'
