Biggar guides it over and narrows the lead to one.

He's brought down over the Chiefs 22, but a penalty is awarded shortly after

Dan Biggar fires another fantastic up-and-under and snaps it out of the air

And we're back. Ospreys to kick off part two

Biggar and Sexton both in v poor form today. Could be an interesting Six Nations...

After a first quarter littered with errors, both sides started to find their rhythm as the half progressed. A single try and four points separating these two. However, the Chiefs are lucky to be marching towards the changing rooms with the lead - Two uncharacteristic misfires from Dan Biggar making hard work of this fixture.

If Ospreys are going to win this, they are going to have to play some rugby. Very poor so far

Ball goes dead and referee calls a close to the half

Biggar tries another up-and-under off the dropout. Doesn't come off this time.

This one swerves wide too. Tremendously lucky for the Chiefs
