Tomas O'Leary has rejoined Munster on a two-year deal.
The London Irish scrum-half will resume his Thomond Park career in the summer having been away from the province since 2012.
O'Leary can then add to the 127 appearances and 57 points he already has with the province since making his debut in 2005.
The Cork man, a graduate of Munster's academy, has made 44 appearances for the Exiles.
With Munster he was a Heineken Cup winner in both 2006 and 2008, as well as claiming Celtic League successes in 2009 and 2011.
O'Leary won the last of his 24 Ireland caps against England at Twickenham in 2012.
Meanwhile, four senior Munster players have signed contract extensions: Andrew Conway, Dave O'Callaghan, Johnny Holland and Eusebio Guinazu. Greencore Academy player Darren Sweetnam has also committed his future to the province.
A bit of a @OfficialCorkGAA feel to our latest contract news - @D93sweets @Tomas_OLeary - physio @ColmCoakley12 will be well pleased.
