Liverpool will have to wait to see how serious Jamie Carragher's injury is. Carragher was withdrawn in the second half of yesterday's 1-0 defeat to Arsenal with a groin injury. Although it's not a bad injury the Reds will have to wait to see how it responds to treatment. "Carra has a problem with his adductor," said Rafael Benitez. "It's not serious, but we will have to see. He couldn't play on and we will see in the next few days how he feels."
