A charging run from Zac Ward makes some good meters for Ulster.

They look to work it through the hands and Tom Stewart then charges forward, but he's not on the same wavelength as Werner Kok, who drops his pass.

Play is brought back for a penalty.

Ulster have done really well to force Cardiff back towards the halfway line, and Tom Stewart then wins the penalty for Ulster by getting his paws on the ball.

Cardiff win the penalty and bring play up to the 22.

They win the throw and the forwards are trying to chip away at the Ulster line.

Stewart Moore is off for a blood substitution and Bradley McNamara is on for his debut.

He's been playing for Instonians in the AIL, so this is a huge moment for him!

It's careless from Ulster, who take the line-out but make a mess of the maul so Cardiff are awarded the scrum.

It definitely looks like it touched a hand on its way through.

It was unintentional from Halfpenny, but it definitely should warrant a knock on.

Halfpenny sends the conversion wide, which isn't something you say very often.

The French officials have decided it didn't touch Halfpenny's hand, which Ulster aren't very happy about.

The try stands!

Ben Thomas looked to pass the ball of Leigh Halfpenny, but the ball came off Ben Carson's head and then the chest of the full-back.

Tom Bowen gathered the ball, chipped it through and beat Werner Kok in the foot race to score.

Did it brush against Halfpenny's hand though?

Cardiff are very quick off the line defensively.

Ulster are playing into Cardiff's hands.

There's some good hands from the Cardiff backs and they're now over halfway.

Ulster have the ball back but Jake Flannery is clattered in midfield to force the visitors back.

In fact, the tackle from Ben Thomas was so good that Cardiff win the scrum.

Bryn Ward thinks he has crossed but Cardiff win the free-kick after the maul was rotated round a little bit too much.

Ulster win the penalty and send the penalty into the corner.

Ulster were Nott stopping the second row from there.

To be fair, it was the parting of the white sea and the second row scores the easiest try of his career.

Now Cardiff win a penalty after some good work at the breakdown.

It's not exactly been a fast and flowing start from both sides.

It's superb defence from Ulster, who stop the maul which forces Cardiff to move it through the hands.

Harri Millard is chopped down and James Hume gets over the ball to win the penalty for Ulster.

Cardiff win the throw and here comes the maul....
