Tom Rogers gets lucky after running back the ball and then going for a chip.

It results in the Dragons counter-attacking and Anzelo Tuitavuki kicking ahead, but the bounce goes the way of Ospreys.

Sadly Marika Koroibete's debut hasn't lasted long.

The wing limps off and is replaced by fellow Australia international Lalakai Foketi.

The enforced replacements are disrupting the flow of this derby.

Dragons bomb a huge chance.

They burst down the left and set Tonga wing Anzelo Tuitavuki running free.

With the last man coming across, he passes to Che Hope but the scrum-half cannot gather.

That had to be scored.

Lovely hands to work Tuitavuki into space but his pass was a little behind Hope.

Another stoppage, and another horrible looking injury.

Rob Hunt - who suffered a serious hamstring injury against Ospreys in Bridgend last season - goes down from the scrum.

The tight-head prop looks in pain with his left wrist. He's very groggy looking.

Chris Coleman replaces him - both Dragons props will have to go the distance.

Sadly that is the end of the night for Wales scrum-half Kieran Hardy, and it looks worrying.

He is helped from the field by two medics, limping off after turning down the stretcher.

His leg just seemed to give way when rushing up in defence.

Reuben Morgan-Williams comes on for Hardy.

Dragons work an overlap down the left and beat Koroibete's attempt to match Santiago Carreras' remarkable kicked interception.

Flanker Harri Keddie goes on the rampage but gets a little too excited and knocks under contact.

Brave tackle from full-back Tom Rogers just outside his 22.

Cagey few minutes here in Newport with Ospreys testing out the Dragons in the air.

Kieran Hardy and Dan Edwards won't want to play much in their own half with the dangerous Harry Beddall sniffing at the breakdown.

Excellent response from the Ospreys.

They stayed calm to level things up after a fast Dragons start and have just tested the defence again with a multi-phase attack.

It is ended by a knock-on in the 22 but encouraging signs, with some hard carries and Tom Rogers looking lively.

Mr Jenkinson has been busy so far in his third URC game, though no fault of his own.

The Irish official penalises Dragons for going off their feet and Ospreys go back into the 22.

Another offence follows at the breakdown and the visitors kick to within five metres.

Big scrum from the Ospreys and they win a penalty.

They kick to the 22 but then knock on from the resulting attempted strike play, then get penalised AGAIN for going off their feet.

Discipline a real problem for the visitors so far.

An early blow for Dragons with the loss of Rodrigo Martinez, who limps off.

The loose-head prop earned a return to the Argentina fold this summer after a strong campaign at Rodney Parade.

Rhodri Jones replaces him and will have a long shift in the front row.

First glimpse of Marika Koroiebete but the former Wallabies wing is well wrapped up by the Dragons defence.

That came after a burst by Wales international Tom Rogers, who has shifted to the full-back position he wants to play after switching from Scarlets.

He's certainly a running threat from 15.

An early Dragons try and Ospreys mistakes, the Rodney Parade crowd are loving this so far.

A knock-on by the visitors in midfield denies them the chance to try and strike back.

Dragons held up over the line but a THIRD penalty against Ospreys inside four minutes leads to a ticking off from Mr Jenkinson.

Ospreys under pressure early on.

Back to the corner.

Che Hope snipes and then Ospreys are penalised again.

Dragons go right into the corner this time. Can Elliot Dee add to his three tries for the season?
