Jamie Roberts has warned that Scotland will be "wounded" after their home defeat to England on Saturday.

Wales host Scotland at the Millennium Stadium on Sunday after they defeated Ireland 23-21 in a thrilling encounter in Dublin.

"We will definitely face a wounded animal in Scotland," Roberts said.

"They deserved to beat England and they will be coming to the Millennium Stadium looking to exact revenge, certainly after what happened two years ago with Shane [Williams's] last-minute try.

"We'll just rest up this week, prepare the bodies, get the minds right and same again from us hopefully."

Wales captain Sam Warburton is still an injury doubt for this weekend after suffering a dead leg against Ireland.
