Sale Sharks star Peel limped off in the second half of Saturday’s game at Cardiff but a scan on Monday revealed no major damage.

Peel is now set to miss just two weeks of competitive rugby and could return in time for Wales’ RBS 6 Nations game against Scotland on February 13.

“The specialist scanned the injury and it’s a groin strain,” said Peel. “Hopefully I should be back in full training in a couple of weeks.”

It leaves Gatland with a selection headache for the RBS 6 Nations opener against England at Twickenham with Cardiff duo Gareth Cooper and Richie Rees as well as Scarlets’ Martin Roberts named as his trio of scrum-halves.

Gatland added: “The scrum-half position is a little bit of a concern for us.

“It is an area at the moment that we’ve got a couple of key players injured, while Gareth Cooper, who has been part of the squad in the last couple of years, hasn’t been selected as a first-choice for the Blues recently.

“We are not 100 per cent sure how long Dwayne is going to be out for. We are just going to assess him over the next few weeks, and when he is back fully fit we will make a decision on him.”
