Wales flanker Dan Lydiate will make his welcome return from injury for Newport-Gwent Dragons on Friday night.
Last season's Six Nations player of the tournament has been sidelined by a serious ankle injury sustained in October last year.
Lydiate missed the entire autumn series and Wales' Six Nations successful title defence, but he will return for the Dragons for their RaboDirect PRO12 clash against the Ospreys in Swansea.
British and Irish Lions head coach Warren Gatland will be delighted to see Lydiate back in action as he considers his options for the summer tour of Australia.
Lydiate will be joined in the pack by Wales star Andrew Coombs, while fellow Six Nations winners Dan Biggar, Richard Hibbard, Adam Jones, Alun-Wyn Jones, Ian Evans and Justin Tipuric will all feature for the Ospreys.
"It's great to welcome home our international boys after they did so well in the Six Nations," Ospreys head coach Steve Tandy said.
"Last season, they came back to us off the back of a Grand Slam and provided the impetus to build on the work done by the core group while they were away that allowed us to kick on and win the league.
"Having won the Six Nations again thanks to a great victory against England, we will be looking for the boys to have a similar impact this time.
"What is really pleasing is the attitude of the boys coming back. I spoke to them all after Saturday, and everyone wanted to be involved in this game.
"They couldn't wait to get back to their region with their team-mates and roll their sleeves up for the cause."
