Leigh Halfpenny handed Wales a huge boost ahead of the crucial England Six Nations
match on Saturday week, as the full-back is finally fit after lingering concussion issues.
The 30-year-old returned to full training with his region the Scarlets last week and will link up with the rest of the Welsh-based Wales players at their Glamorgan training base on Wednesday.
Halfpenny has not played since being knocked out by a late tackle from Australia centre Samu Kerevi in November.
He has struggled with headaches and concussion symptoms, and has had to visit a specialist, but is now ready to return.
His regional coach Wayne Pivac said: 'It's great to see him running around with a smile on his face.
'To do full contact he has got to be symptom free and Leigh has been symptom free, he trained with us last Thursday and Friday and yesterday he did everything, full contact, full tackling.
'We had a mini-game scenario, what we call level three which is a game scenario so there is no hiding places.
'He was taking high balls, getting clattered. He did everything he needed to do.
'He goes back to Wales available, we feed back information, medical team to medical team and I have passed a little note on to Warren.
'Warren will make a call on what he does from there. I think we are going to get a message on who, if any, are going to get released after Wales training on Wednesday.' The news that the two-time Lion is available for the Six Nations decider in Cardiff is enormously positive for Wales - especially after seeing England kick Ireland and particularly France to death in the opening rounds.
Halfpenny is a bomb-defusal expert and one of the best in the world at fielding the ball in his own 22 under pressure.
England scored four of their five tries on Sunday from neat grubbers into French territory, exploiting the ploy ruthlessly.
Liam Williams has played well at full-back in Halfpenny's absence, and Josh Adams has starred on the left wing. George North scored two tries and was named man of the match in Paris on the opening night too, so Warren Gatland has a dilemma on his hands on who to pick in his back-three.
Rhys Patchell, the Scarlets fly-half, is also fit but more likely to play for his region this weekend after hamstring trouble has kept him our since December.
'If they feel they need a game we will certainly help them in that respect and slot them in this weekend if required,' added Pivac.
