The 27-year-old, who has only just returned himself from a long-term knee injury himself, will win his 24th cap in Cardiff.

Hines has not recovered in time from two knocks picked up in Sunday's defeat against France but Scotland boss Andy Robinson believes his side couldn't have found a better replacement.

"I welcome Jim back into the squad following his own recovery from injury,” said Robinson.

"We're going with Jim as he's like for like with Nathan and will help us to get a platform as we look to get our mauling game going. Jim is also an experienced player."

Scotland team doctor James Robson said: "Nathan suffered a calf strain and aggravated an old ankle injury during the match at the weekend."
