Brian O'Driscoll says he is a relieved man to be over the hamstring injuries that have featured throughout his career, as he prepares to win his 100th Irish cap against Wales at Croke Park.
The 31-year-old, widely regarded as one of the best players in the last ten years of the game, has come up with a specialised stretching routine that appears to have ended all his concerns over his hamstrings.
O'Driscoll does, however, remain wary of tempting fate.
"At times it was difficult not knowing where it went wrong with the hamstring injuries," he said.
"Generally I think I've been fortunate with injury so far. The dislocated shoulder after the 2005 Lions tour was the serious one.
"But the hamstrings also suffered for a couple of years and while that has been addressed, it's still a work in progress.
"It makes it easier knowing my hamstrings don't feel tight when I play. I don't have that at the back of my head at the moment."
O'Driscoll becomes the second Irish player in a fortnight, after John Hayes, to earn a century of caps for his country.
