Cory Allen: Wales and Cardiff Blues centre out for three months

Cory Allen made his full Wales debut against Argentina in November 2013

Wales centre Cory Allen has confirmed he will be out of action for 12 weeks with a hamstring injury he suffered in Wales' win over Uruguay.

The Cardiff Blues player, 22, scored a first half hat-trick in the 54-9 win but was taken off in the second with a "significant" hamstring injury.

He was subsequently ruled out of the tournament and replaced by Newport Gwent Dragons' Tyler Morgan.

"The injury is a massive disappointment but these things happen," Allen said.

"I had a scan the morning after which pretty much confirmed what everyone expected, that I'd torn my hamstring and there was also a grade three tendon tear as well.

"I went up to London to see a specialist and his advice was that I have an operation.

"I'm back off to London on Tuesday to have the op."
