Jennings has agreed a three-year deal with the Irish province after what will be a two-year stay in the Guinness Premiership with the Tigers.

Leinster chief executive Mick Dawson added: "We are delighted to announce that Shane has re-signed with the province.

"Shane is an accomplished forward who will add greater competition to the Leinster back row.

"He has shown outstanding leadership qualities throughout his career and we look forward to welcoming him home to Dublin next summer."
