Brian O'Driscoll has a plethora of achievements to his name.

And one of those is the former Ireland captain's test match record.

With 141 caps for Ireland and the Lions, the Off The Ball guest presenter is the most-capped player in test rugby history.

Or at least he will be until New Zealand's captain Richie McCaw equals it tomorrow.

The All Blacks flanker, who made his debut against Ireland in 2001, is on 140 caps and has been named in the team to face Southern Hemisphere rivals Australia in The Rugby Championship - which means he will equal O'Driscoll's record.

And with the Rugby World Cup on the horizon, the 34-year-old flanker is likely to amass many more caps.
