Glasgow respond immediately and Duncan Weir fires a fine kick between the posts from distance. More admirable because of the swirling wind.

 Connacht finally make their pressure tell as AJ MacGinty kicks the penalty after an offside decision.

Andy Nicol on BBC Scotland: "There is more zip to Glasgow this time.  Two weeks ago Connacht's line speed really dictated but tonight Glasgow's line speed in defence has been outstanding."    

Full-back Tiernan O'Halloran touches down in the corner after a flowing Connacht move. But the referee checks for a knock-on earlier in the move by Bundee Aki.  

Matt Healy makes a superb break from his own half across the halfway line, but the Connacht man is finally taken down before Glasgow clear.

Glasgow win a penalty, but Duncan Weir kicks for touch instead of taking what would probably be an easy three points.

Fraser Brown squanders the opportunity with an overthrow at the line-out.

AJ McGinty awkwardly screws a clearance kick into touch with Glasgow at last close to the Connacht try line.

The referee is having a word with Glasgow captain Jonny Gray about the number of penalties the visitors are conceding. It was Ryan Wilson penalised this time inside the Connacht half.

Glasgow survive a spell of pressure with a turnover and Stuart Hogg hoofs it clear.

However, Duncan Weir is caught and Connacht win the penalty as the home team apply increasing pressure.

It has been an exhilarating start, with both sides determined to run at the opposition. Connacht back on the attack.

Andy Nicol on BBC Scotland: "It is a terrible start for Glasgow. Finn Russell would have trained all week and, with the nice weather, they would have wanted to play a fast-track game, which Finn is so well suited for. Glasgow need to re-group now. They can't afford to let this affect them."

Kieran Marmion makes a break, but Glasgow breath a sigh of relief as the Connacht man loses his footing. Glasgow scrum.

D'Arcy Rae is a replacement for Zander Fagerson for the moment as the game re-starts with a scrum.

Finn Russell is being lifted on to a stretcher, with Duncan Weir his replacement at fly-half, while Zander Fagerson is off at least temporarily.

A double blow for Glasgow within seconds of the start.

Two Glasgow players are on the deck already after what looks like head knocks. Concern for Zander Fagerson and Finn Russell.

Connacht get the game underway and Glasgow take immediate safe possession despite a bustling wind.

The Connacht players enter to a rapturous reception moments after a more subdued greeting for the Warriors.

We are a few minutes from kick-off and the Connacht fans are making it a noisy place.
