Jamie Roberts returns to the Wales team on Saturday for the first time in what he describes as "a very long six months."
The Lions centre will win his 45th cap against Argentina, his first appearances for his country since Wales won the Six Nations Grand Slam.
Since then he has had to undergo an operation on a knee injury, forcing him to miss the summer tour of Australia, where they were narrowly beaten in all three Tests.
And on Thursday it was confirmed that he will leave Cardiff Blues at the end of the season, with Racing Metro his likely destination.
"When you miss a campaign, a summer tour, it makes you appreciate it more and more. I can't wait for Saturday," Roberts said.
"It has been a very long six months. My last memories I have in a red shirt are of walking around the pitch after the France game with the Six Nations trophy.
"Anyone who has had a cruciate knee reconstruction will tell you they are not very nice. You go to hell and back with the rehabilitation. It's tough.
"But rugby is tough. You have injuries and setbacks and you have to climb the mountain again. When you have a serious injury you start again from the bottom.
"I can picture what the changing rooms must have been like in Australia and I am sure the boys who were out there will use it as motivation for this autumn series.
"To go that close to a team like Australia in their own back yard will hurt the guys and hopefully we can do the job this autumn."
