Munster Head Coach Rob Penney has named a strong starting XV for the crunch Heineken Cup clash against Perpignan at Thomond Park on Sunday (ko 12:45pm).
Current members of the squad besides O'Driscoll, to have played 200 times are Ronan O'Gara, David Wallace and Marcus Horan while the others are the returning Peter Stringer, the recently retired Alan Quinlan and John Hayes and current Forwards Coach Anthony Foley.
Just turned 32 O'Callaghan made his first start for Munster in August 1998, in the pre season friendly against Edinburgh Reivers in Musgrave Park.
The first of his 82 Heineken Cup caps came off the bench in October of that year against Perpignan and after the 2002/2003 season he established himself alongside Paul O'Connell as the regular Munster second row pairing.
Twice a Lion (2005 & 2009), he captained them in South Africa against the Southern Lions June 2009 and has been capped 85 times by Ireland.
