Sam Davies comes on for Ospreys fly-half Dan Biggar who is hurt as he tried to ground the ball. It's a shame Biggar couldn't get the ball down after a nice break.

After numerous replays from a variety of angles TMO Derek Bevan rules that Dan Biggar did not ground the ball.

Dan Biggar slices through the Glasgow defence and dives over the line but did he get the ball down? Rob Harley and Nikola Marawalu combine to try and stop him from grounding the ball. George Clancy refers the decision to the TMO.

Edinburgh are beginning to warm to their task at Rodney Parade, edging their way into Dragons territory.

The visitors have won two penalties from scrums, an area where they dismantled the Gwent region during last month's Challenge Cup semi-final.

But Dragons discipline is holding up and they are keeping Edinburgh at bay.

Great defence so far from Newport Gwent Dragons.

It's very tiring defending all the time but their structure looks very good.

They're suffocating Edinburgh at the moment, who are a bit devoid of ideas.

Duncan Weir makes no mistake with his second effort from just outside the 22.

Tyler Ardron is penalised for infringing at a line out, but Glasgow's Duncan Weir's effort is just wide of the posts. The Scottish fly-half struggled to contend with the swirling wind at the Liberty Stadium.

Edinburgh were comprehensive 45-16 winners when these sides met in the Challenge Cup semi-finals three weeks ago, but the Scots have looked a little rusty so far.

The visitors have yet to create any scoring opportunities or keep possession for long periods, primarily because the fired-up Dragons have started this game in such tenacious fashion.

Plenty of you seem to appreciate the magnitude of this game for Ospreys...

Anujan from London tweets: "Big game this, gotta do what you can #Ospreys"

The Swifts write: "Big game in #Pro12 tonight. Ospreys need home draw for semi final. Big ask to beat this Glasgow side at the moment though."

While Stuart Dempster is remembering days gone by: "Remember when #ospreys had a backline of Phillips, Hook, Williams, Henson, Bishop, Bowe and Byrne"

The strongest Ospreys' backline of all time, Stuart?

The first real break of the game from the Ospreys as centre Josh Matavesi's offload releases Tyler Ardon just inside the Glasgow half. The forward is stopped inside the visitors' 22 and the Scots manage to turn the ball over and clear their lines from the next phase of play.

If Ospreys win this one, I fancy them to get a home tie in the play-offs.

The Ospreys have named their ground after one of their fans for tonight's clash. It will be called the Katie Phillips Stadium after the 18-year-old from the Mayals area of Swansea. She won a competition organised to celebrate the region's move to the venue 10 years ago.

Dragons have made an excellent start at Rodney Parade, close to scoring the opening try within two minutes.

After a rolling maul - which has been a potent weapon for Dragons this season - the hosts have gone close with powerful carries from Tyler Morgan and Taulupe Faletau, but Edinburgh are holding on for now.

Dan Lydiate's name is on the team sheet for Wales every game automatically and he was a great British and Irish Lion, but James King has been playing well for Ospreys and the rest of the team are probably so confident with the way the forwards are playing that to adopt him into the game won't be difficult at all.

I can't see them changing a thing about the way they play.

Dragons fly-half Jason Tovey makes no mistake with a short range penalty.

And we're off

"Ospreys are only four points behind and they too are playing for a home play-off, so we're expecting an extremely tough game at the Liberty Stadium.

"They have played at a consistently high level throughout the season and have a good balance in their play - a strong, aggressive defence allied to an excellent attacking game.

"We will need to put in one of our best performances of the season to come away with a positive result."

Both teams are out on the Rodney Parade pitch, with Newport Gwent Dragons entering the fray to a cacophony of fireworks and flames.

The players and their fans seem fired up, determined to avenge last month's crushing defeat to Edinburgh in the European Challenge Cup semi-final.

The Dragons were were hurt by that performance against Edinburgh in the European Challenge Cup. They need to bounce back after that humiliation.

I spoke to coach Kingsley Jones just before the game tonight and he thought there was a good buzz and atmosphere amongst the players.

They're looking a bit psyched up.

If it comes down to kicks, both the Ospreys and Warriors are both well equipped to win.
