Ulster go really close to getting over the Ospreys' line, but they knock-on and it will be a visiting scrum.
There have been too many handling errors tonight from the home side, but from their perspective at least with four minutes remaining they are in the right area of the pitch.
Ospreys with the ball in hand inside the Ulster half, but they are going nowhere fast and the pressure finally tells when the hosts win a scrum 30 metres from the Ospreys line.
The Ospreys were getting close to the Ulster line after an attacking lineout, however, Stuart McCloskey gets himself on top of the ball to win a penalty and allow Nathan Doak to clear to touch.

Nick Timoney (conv. Nathan Doak) (56 mins)
It is a try for Timoney and an assist for his teammate Stuart McCloskey.
With the ball moving from right to left, McCloskey looks like he is going to carry into the Ospreys' 22, but instead throws a fizzing low pass to Timoney who races away into the left-hand corner for Ulster's fourth try of the evening.

Jacob Stockdale (conv. Nathan Doak) (47 mins)
Ulster do make the breakthrough this time.
An attack on the 22 sees the ball spun right into the arms of Stockdale who made a great angled run and he bursts through a challenge before scampering over for the try.
The home team look threatening as they go through the phases after winning the lineout. However, Jake Flannery's kick to the right flank is short and forces play in-field.
Ulster do go over the line eventually but it is a mess of bodies and the ball is held up. Goal line clearance for Ospreys.
