James Hook: Scotland have something to prove

James Hook has warned that Scotland will be out to prove a point when they visit Wales in the Six Nations on Sunday.

Scotland were defeated by England at Murrayfield on the opening weekend of the tournament, while Wales triumphed over Ireland in Dublin.

"Scotland will be tough opponents after losing to England," Hook said.

"They will have something to prove, so we have got to be aware of that.

"But there's more to come from us and we will be looking for improvements for next week."

Scotland stand-off Dan Parks announced his retirement from international rugby with immediate effect following their defeat to England.
