10 minutes left here and Ospreys are on the attack. Can they regain the lead?

Great chance for Ospreys! Fantastic break from Jeff Hassler who runs from deep inside his own half to the Ulster 22. Quick ball from the ruck as Ospreys go wide but Tyler Ardron knocks on. Ulster scrum.

Conditions still awful here at Ravenhill. Scrappy scrappy game here. Ospreys trying to keep it in the forwards.

Scrappy play from both sides knocking the ball on. Ulster have scrum just outside the 22 but attack comes to nothing.

Ulster applying pressure but Ospreys managing to keep the, out at the moment. They turnover and Sam Davies clears.

Conditions taking its toll on the game. Lots of stoppages.

Drama here at Ravenhill. Ball was stolen just as Iain Henderson was going over the line and Ospreys will have the 22 dropout. Nigel Owens had initially awarded the try but TMO rules it out.

Game has slowed down a bit here. Ulster have gained great field position after Darren Cave's kick into the corner.
