Wales fly-half Stephen Jones is in line to make his comeback for Clermont Auvergne a week ahead of schedule in Sunday's European Cup Pool Four clash against the Ospreys.
Jones suffered a double sprain of his right ankle on October 1 that was due to keep him out for a month and left his hopes of playing for Wales against New Zealand next weekend on a knife-edge.
But Jones has been included in a 24-man Clermont Auvergne squad that is looking to bounce back from last weekend's 57-23 defeat to Leicester.
The Ospreys produced a shock win over Stade Francais last week, but head coach Lyn Jones refuses to underestimate a Clermont side brimming with internationals.
"Although we were delighted with last week's result against Stade Francais, it is one thing to beat a French side when you are at your home ground, but it is a totally different proposition when you are playing them in their own back yard," he said.
"Clermont are a quality side and they will have been disappointed with their result against Leicester.
"They have a strong pack of forwards, and in players such as Stephen Jones, Pierre Mignoni and Aurelien Rougerie they have real quality behind the scrum."
Wales lock Brent Cockbain and hooker Huw Bennett return to the Ospreys side while James Bater starts on the blind-side flank with Jonathan Thomas moving to number eight.
"Brent Cockbain and Huw Bennett in particular have trained well over the last few weeks. James Bater returns from injury and will be keen to make an impact at the weekend." Jones added.
