Now it's Dragons getting sloppy.

They give away a free-kick for taking too long at a lineout and after Jack Walsh opts for an up-and-under, the ball is knocked on by the visitors.

An attacking scrum for Ospreys - albeit an uncontested one as the away side have no fit front rowers to come back on.

Fair play to the Ospreys, they believed and they went through the phases, they made the correct decision to go for the corner and it’s paid off.

The tactics were there, and they get the rewards.

A big 5 minutes to come.

No try as Ulster are adjudged to have made a double-movement.

Ulster are over the line but did they get it down?

Jack Walsh goes for the corner and nails it.

Big chance. Big moment.

Ulster tap and go in search of a bonus point try but Zac Ward is bundled into touch. Another penalty coming and they go again with the clock in the red.

Big moment.

Dragons down to 14 men and are forced into a front row change.

Cebo Dlamini can have little arguments. He went high and made head contact. End of.

Hearts in mouths there in Belfast as David Shanahan throws a wild pass that is intercepted. It would have been a long way to go but there was a penalty coming anyway.

He'll tell you he knew that...

Ben Connor is reviewing head contact from Dragons prop Cebo Dlamini here.

It's following his hit on Harri Houston...

A chip ahead from Jack Walsh but it's too far ahead of Daniel Kasende.

Angus O'Brien wins the race to ground the ball behind his own line and the Dragons have a drop out.

Ulster will be thinking "is history repeating itself here?"

Ill-discipline again and giving away easy decisions might cost them.

Replacement number nine Rhodri Williams is doing a good job in taking the sting out of this.

He's allowed five seconds, in theory, before passing away from a ruck. The Dragons man seems to be using up 4.99 seconds of that every time.

Superb Ulster defence on their own 5 metre line! A training ground line-out move from Cardiff almost catches Ulster out but their scramble defence is good and, despite the visitors going through the phases, Ulster hold them out and, eventually, win a turnover penalty.

That could be huge with just four minutes left on the clock.

Ospreys are frustrated again but this time it's not a knock-on, but a great turnover from Dragons flanker Ryan Woodman that ends the attack.

Tinus de Beer then wastes no time in hammering the ball downfield and the visitors have some respite.

Ospreys Coach, Duncan Jones speaking on S4C -"The ref has to make those decisions, and with the game in that area of the field is important.

'We need more accuracy and fair play to the Dragons for exploiting that.

'Hopefully we can find a way through, we need to make the right decisions, we need to be accurate and get us over the finishing line."

Deja vu.

This time the pressure really is sustained as Keelan Giles and replacement prop Rhys Henry both go close.

With the Dragons hanging on for dear life, Marco de Witt charges for the line but the South African is too upright and knocks it forward in contact.

You feel it's coming here for Ospreys if, and emphasis on if, they can tidy up these errors.

Under pressure, Angus O'Brien can only clear 20 metres and another Ospreys chance here.

Slowly, they are cranking up some pressure here.
