Aston Villa manager Martin O'Neill has confirmed that Norwegian striker John Carew will be out for up to six weeks after sustaining knee ligament damage.

Carew, 28, scored the opener in Villa's 2-0 win over Everton on Sunday but was forced off after 53 minutes.
O'Neill told Villa's website: "We're looking at four to six weeks out - it's a blow because he is a key player.
"We play Tottenham and West Ham before an international fortnight so from that standpoint he could have missed more."
Carew's goal was his first of the season for Villa and O'Neill believes it was just reward for the work the Norway international does for the team.
"You can do an awful lot of work as a centre-forward outside the penalty area, but you're there to get goals and he's off the mark now.
"Suddenly, all that good work he has done for us, that seemingly has gone unnoticed, he'll start to think now that there is a bit of justice."
