Legendary Welsh winger Shane Williams says he would have told the British and Irish Lions to stick their invitation to play in Tuesday's tour game against the Brumbies if he thought for one second he wouldn't have been good enough.
Williams, 36, was named international player of the year in 2008, went on two Lions tours and played 87 Tests for Wales.
He retired from Test rugby at the end of 2011 and has been playing for Japanese club Mitsubishi Dynaboars.
With several Lions backs injured, Williams got a call from Lions assistant coach Rob Howley late on Saturday night.
Also getting call ups were winger Christian Wade, who was on tour with England in Argentina, and South African-born England centre Bradley Barritt, who had been vacationing in Los Angeles, but hasn't played since late April due to a leg injury.
All three were rushed into the starting team to play the Brumbies in Canberra.
"Of course (playing in Japan) is not going to be to the standard we play tomorrow," Williams said.
"However, I have kept fit and I've worked just as hard in Japan as I have throughout my rugby career, so hopefully it's not going to be too much of a shock to the system.
"I've played enough professional games and enough international level games to know what to expect tomorrow.
"If I felt for one second that I wasn't going to be ready for this game, not good enough for this game, I would have told Rob where to stick it.
"To be given this opportunity again is a dream come true completely out of the blue, I knew nothing about it.
"But I appreciate the Lions have had a lot of injuries during this tough series so far and if by me playing tomorrow helps the Lions recover and do whatever's best to prepare for the game on Saturday and win that game, then I'm very proud to be part of it."
Lions doctor James Robson said centre Jamie Roberts (strained hamstring) was in grave doubt for Saturday, but was optimistic about his prospects for the last two Tests.
He said blockbusting winger George North (hamstring) had a great chance of being fit for Saturday, while centre Manu Tuilagi (shoulder) is progressing well and a decision on his availability for Saturday would be made later in the week.
Winger Tommy Bowe (broken hand) is still on track to be available for the second Test in Melbourne on Saturday.
