FT: Ulster 36-12 Ospreys
That's all from us in Belfast as Ulster move up to fourth in the URC table with a third win from five games.
With Andy Farrell's Ireland squad for the autumn internationals, it was a fine time for Jacob Stockdale to offer a reminder of his finishing ability too.

Jacob Stockdale (try) Nathan Doak (conv) - 66mins
What a try for Stockdale.
Ulster spin the ball right to left and substitute James Humpreys is the image of his dad David as he whips a 30-metre pass out to Stockdale on the wing.
The big winger then goes outside Keelan Giles and manages a superb touchdown at full stretch in the corner. Superb.
Nathan Doak shows the head coach Richie Murphy what he is about by nailing the conversion from the left-side touchline.

Ulster 29-7 Ospreys
Better from the Ospreys.
The visitors attacking down the right and the wily figure of Justin Tipuric shows some great hands, but the ball runs into touch for an Ulster lineout. Better.

Ulster 24-7 Ospreys
Ulster demolish the Ospreys scrum and run from deep.
The ball ends up on the left flank and Mike Lowry skips between two defenders when he had no right to.
He enters the Ospreys 22 and offloads in the tackle to John Cooney but the ball spills and Ospreys regather. Impressive pace throughout the Ulster side.
