Glasgow win a penalty to ease the pressure as the scrum collapses. Most of Scotstoun releases a sigh of relief.

Tommy Seymour goes off with a cut on his head and is replaced with DTH van der Merwe on the Glasgow wing.

Ulster win a scrummage just short of the Glasgow line after the visitors win a strike against the had in the Glasgow half and apply wave after wave of attack.

"Ulster have had the better of the first-half so far, just as they did at Scotstoun on Saturday. Glasgow came back to blow Ulster away in the second period in that match, but the visitors have many more experienced internationals in their ranks this evening, and they'll provide stiffer resistance to any pressure from the Warriors."

Glasgow at last begin to apply some pressure and they claim for obstruction after Niko Matawalu goes down as he tries to reach a high ball. Glasgow do win a penalty, kick for position and waste the opportunity with poor line-out ball.

"Glasgow are being bullied out of it and are playing second fiddle, but it is still only 8-6. It is the same as last week, when Ulster dominated for 50 minutes."

Ruan Pienaar misses the conversion attempt as his kick screws wide of the far post.

Ulster might be behind on the scoreboard, but it is the visitors who are dominating possession and Chris Henry touches down in the corner after a superb flowing move.

Tommy Seymour puts in a superb saving tackle on Tommy Bowe as the Ulster winger threatened to touch down in the corner.

What a kick that is. Wind assisted in truth, but there was never any danger that it was not going to fly high between the posts. Stuart Hogg puts Glasgow ahead for the first time.

Glasgow's Stuart Hogg is about try a monster of a penalty kick from his own half.

"Ulster are just winning the physical battle for me. They are a little bit more committed and the front two Ulster men are doing more damage than the front two Glasgow men at the minute."

Niko Matawalu is better known as a scrum-half, but he shows his prowess on the wing to intercept a dangerous Ulster move.

Glasgow hooker Dougie Hall is also retiring at the end of the season, with the likes of Sean Maitland, DTH van der Merwe and Niko Matawalu moving on to other clubs.

It's an emotional occasion for Glasgow captain Al Kellock, who makes his last appearance at Scotstoun before retiring at the end of the season. He'll be hoping his playing career doesn't end here this evening. He wants to bow out with another Pro12 final appearance - and preferably with a winners' medal in his back pocket.

Ulster number eight Roger Wilson is penalised this time for not rolling away and Finn Russell levels the scores.

By the way, Tommy Seymour started the game for Glasgow after all after that injury scare during the warm-up.

The visitors win a penalty within 40 seconds, after Rossouw de Klerk is penalised for not rolling away. Ruan Pienaar slots the easy kick between the posts.
