Weir kicks off an all-important 40 minutes for the Ospreys. The Pro 12 champions sit fourth in the table, and a loss tonight would leave their title hanging in the balance...

Adam Jones gifts Glasgow with yet another penalty, and Weir gets the opportunity to finish the half on a positive note. The ball splits the uprights and Rolland signals the break. Warriors playing some exciting rugby against an unimaginative Osprey side. The visitors look passive and disorganised in defence and are content to simply absorb the Warriors' pressure. They now face the difficult task of closing a nineteen point gap.. Comeback looks highly unlikely..

The scrums have been a disappointing aspect of the game so far.. Not once has the ball filtered through the back on the first time of asking. Alain Rolland losing patience.

Prop forward Grant crosses twice within thirty minutes. Phenomenal work rate from the hefty Warrior. Glasgow once again break into the Osprey half and steadily grind towards the try-line. Then Fotuali'i sparks the attack down the blind-side. Some superb handling followed by a glorious off-load from Fotuali'i sends Grant through for the try!

Relief for the Ospreys as Weir draws another one wide. Grant concedes the penalty at scrum-time..

We're hearing that Hibbard has injured the inside of his left knee. Not sure how serious..

But the prolonged period of pressure comes to nothing, and the Warriors are rewarded for their discipline and organisation in defence.. An Osprey player flops over a ruck and is rightfully penalised.

Ospreys currently on the attack, just outside the Warrior twenty-two. They're patiently building the phases, inching toward the whitewash..

Minutes later, Glasgow secure try number two. They find themselves on the half-way, sweeping the ball from left to right in search of space. The slow progress frustrates Matawalu though, so he delivers a perfectly weighted kick down the right hand wing. Maitland provides the chase and dots down, an inch from the touch-line. TMO is consulted, but he gives the go-ahead!

Hibbard injures himself in the tackle and can't continue on. Baldwin fills in.
