Wales and Ospreys lock Brent Cockbain says he is determined to re-establish himself for region and country.
Cockbain has been out since last November
The Lions tourist, 31, won the last of his 22 caps against Fiji last November when he suffered a detached hamstring.
That kept him out for the season, but the Cairns man came through his first full-contact game in a training match with the Ospreys on Wednesday.
"It's up to me to prove I'm still a force to be reckoned with and show the youngsters a bit," he told BBC Sport.
"I've had 10 months being a normal person and it's funny coming back!
"But it's great to be with the boys again and it was encouraging how good the leg felt."
It would be sensational if I could get back into the international reckoning after the injury I had
Cockbain saw Ian Gough take his place in the Wales boiler room alongside Robert Sidoli last season.
But it was Ospreys pair Alun Wyn Jones and Ian Evans who really came through to put Cockbain's regional and international places under threat.
The rugged youngsters made the Ospreys second row-berths their own and went on to shine on Wales' summer tour to Argentina.
"They did very well in Argentina and are undoubtedly the players of the future," Cockbain told BBC Sport Wales.
"I'm a realist, I've got to get playing then bring my aggressive, rough game to the fore.
"I'll see how it goes with the Ospreys before worrying about getting noticed by Wales.
"It would be sensational if I could get back into the international reckoning after the injury I had."
