Ospreys are going through the phases once more, any yellow card for Lyon here could be crucial with around 15 minutes left to play in south Wales.

The final penalty is in front of the posts, so another interesting decision for Ospreys.

They opt for the 'tap-and-go', and Dewi Lake makes good yards towards the try-line.

Lyon were warned in the first half, and referee Andrew Brace dishes out the same caution once again.

Next one and the card will be out.

The home crowd in the Swansea.com Stadium are calling for a crowd, as several penalties in succession go against Lyon in their own 22.

Ospreys are finding it difficult to break down this powerful Lyon defence, but inch by inch they are creeping closer.

Another penalty goes the way of the Ospreys, who are now just outside the Lyon 22 with the line-out.

There is plenty of time left in the game and you don't want to be panicking.

Valentin Simutoga won his side a penalty a moment ago, but now he is the villain as he's conceded a penalty at the scrum.

Dan Edwards finds touch near half way, and Dewi Lake is at the back of an effective driving maul.

Let-off for Ospreys.

Lyon drop the ball forward in the driving maul, which was picking up a head of steam.

Straight from the restart Valentin Simutoga gets over the ball at the breakdown and wins the penalty for Lyon inside the Ospreys 22.

Not the exit Mark Jones would have been wanting from his side.

Dan Edwards' penalty sneaks the right side of the left post, and Lyon's lead is cut to seven points.

Ospreys have responded well since that Lyon try, and have won a penalty in the middle of Lyon's half after a late hit on Dan Edwards.

A chance to reduce the deficit to one score.

It was a well-worked try and it was just the power game.

These guys who have come on at half-time are just huge men.

"Short" is the call from referee Andrew Brace, but Lyon are knocking on the door.

The Lyon scrum holds firm, and the French side clear their lines.

They then launch their first real attack of the second half, working their way past the Ospreys' 10-metre line.

Ospreys' turn to defend.

It was a great initial carry from Jac Morgan but the scramble defence from Lyon is unbelievable.

Ospreys are losing their shape a little bit about 10 or 15 metres from the line.

James Fender is held up in the tackle by Lyon, but they will need to be better at this scrum than they were in the first half.

Ospreys have started the second half as they ended the first, firmly on the front foot.

The hosts are already into the Lyon 22 and threatening to take the lead.

The concern for Ospreys was always the potential strength of the Lyon replacements bench and the visitors have made five changes at half-time.
