Ulster form the maul from the lineout and make their way to just outside the Leinster 22 only for the ball to go forward. Scrum to Leinster.

Madigan's kick out of hand is poor with Gilroy collecting and from there Ulster are able to earn the penalty. Jackson kicks to halfway.

Van der Meerwe loose pass is stolen by Boss and Leinster get the turnover.

Paddy Jackson gets the game underway.

This should be an exciting game! How are the pitch conditions? (As in, will weather be an issue for this match?)
