Looks like Aurelio just moved into "must-have" status.
Tough day for Liverpool, losing not only Riise, but having Carragher limp off and dropping 2 points to Sheffield United. How much of this "loss", if you can call a tie a loss, can be attributed to their imminent trip to Kiev to play Maccabbi Haifa?
UPDATE, from Clubcall:
Reds boss Rafa Benitez confirmed that Carragher will definitely not face the Israelis but Riise, who suffered a sprain, has a small chance of being available.
LATER UPDATE, from Yahoo! Sport:
Scans today have shown that England defender Carragher has sprained a medial ligament while Norway international Riise has torn lateral ligaments.
A Liverpool spokesman said: "We expect both players to be unable to train for the next two to three weeks."
