Brian O'Driscoll will win his 100th cap for Ireland in Saturday's RBS 6 Nations clash with Wales at Croke Park.

The Lions skipper took a blow to the head in the 20-16 victory over England but has been passed fit to lead the defending champions for a 63rd time.

O'Driscoll is the 14th player to join the ranks of rugby's centurions, one match after John Hayes became the first Irishman to reach the landmark.

The 31-year-old said: "At the start you want to get as many caps as possible, but you never look and hope to attain 100.

"I've always approached it like the next game in a green shirt is my last. With that policy you can't go far wrong. And it's not over yet."

Head coach Declan Kidney has decided against making any changes to the starting line-up that edged England in a brutal Test at Twickenham.

Rob Kearney has recovered from the knee injury sustained against France but Kidney has opted to retain Leicester's Geordan Murphy at full-back.

Kearney is included among the substitutes, however, with Andrew Trimble dropping off the bench in the only change to the 22.

Number eight Jamie Heaslip sustained an ankle injury against England but has been given the green light to take his place in an all-Lions back row that also features Stephen Ferris and David Wallace.

Jonathan Sexton, who impressed amid pressure-cooker conditions at Twickenham, continues at fly-half with Ronan O'Gara included on the bench.
