Ulster defeat Glasgow in a hard-fought fixture at Scotstoun as the Irish team move to the summit of the Pro12 table.

The visitors had two tries disallowed either side of a Darren Cave try, before a penalty try just before half-time gave Ulster the advantage at the break.

Glasgow were the stronger side in the second half, with Tommy Seymour going over in the corner.

Ulster's backline combined well to allow Paddy Jackson to skate over the Glasgow try line to respond to the Scottish side's fightback.

Ulster held on to secure a crucial four points and make it four wins out of four to stay unbeaten this season.
