World Player of the Year Johnny Sexton has signed an IRFU contract extension that ties him to Leinster and Ireland until 2021.

Sexton has had an incredible year with both province and country. The 33-year-old won a Grand Slam, a series in Australia and steered Ireland to a famous defeat of the All Blacks in Dublin.

With Leinster, he swept to an unprecedented Champions Cup and Pro14 double.

The outhalf - who had a two-year spell in France with Racing 92 in 2013 - pulled the strings in all of those successes and wraps up 2018 by committing his future to playing in this country.

"I am delighted to sign a new IRFU contract to continue to play for Leinster and Ireland," he said.

"It is where I have always wanted to play so I am delighted to extend. We get looked after extremely well here and it is an exciting time for Irish rugby. I am looking forward to hopefully being a part of that over the next few years."
