Dan Biggar is set to miss Northampton’s Premiership game against Harlequins on Sunday with a leg injury picked up in the England win.
“Dan has got an injury that he is nursing and we are very optimistic for next week,” said Wales assistant coach Stephen Jones.
"We’ll find out on Monday but the reports are that we are pretty optimistic that he is going to be available to us. It’s good from that aspect. I’m not sure (what the injury is), you’ll have to ask the medical team.”
Jones also commented on Kieran Hardy, saying:
“For Kieran, it’s unfortunate after having a wonderful performance against England. He has picked up a hamstring injury and is unavailable for the rest of the tournament. Where that leaves us with scrum-halves is simple, we have got three left in the squad who are good to go. Tomos is ticking the boxes (after his injury), which is great, and he is taking part in training.
“It’s unfortunate for Kieran. He has worked particularly hard on his game to improve aspects and he is a very fit guy, works hard on his fitness. We thought his performance at the weekend was excellent. Unfortunate for him he is not in a position to be able to back that up.”
