And the first major thing that happens after Taine Basham comes on is the referee is annoyed with the Dragons discipline and he turns a scrum into a penalty for Sharks.
Replacement
Dragons 6-12 Sharks
There is a change at half-time with Wales squad flanker Taine Basham on for Ollie Griffiths.
Kick-off
Dragons 6-12 Sharks
Dragons full-back Cai Evans kicks off the second half with the wind at his back.
A six-point deficit they need to address.
Ospreys eyeing potential Sale clash
HT: Dragons 6-12 Sharks
In south-west France, Bayonne have a bonus point in the bag and lead Dafydd Jenkins' Exeter Chiefs 26-7 at half-time.
So unless Chiefs pull something remarkable out of the bag, Ospreys will host Sale in the next round of the Challenge Cup.
It also means Bayonne could be heading to Rodney Parade if Dragons can turn things around.
Brown back in action
HT: Dragons 6-12 Sharks
One thing that has been good to see is Wales prop Leon Brown making his first start of the season.
He has had so many injuries but is in the Six Nations squad and Warren Gatland will be hoping this will be his breakthrough tournament.
Half-time Dragons 6-12 Sharks
So Dragons looked comfortable as they led 6-0 in the opening 30 minutes with two Cai Evans penalties.
Then they concede two tries just before half-time for Jaden Hendrikse and Ox Nche and the complexion changes.
Dragons will have the elements in the second half. Is that a six-point wind? Time will tell.
Try - Dragons 6-12 Sharks
Ox Nche
The Dragons appeared to have kept Sharks at bay but have conceded a couple of tries just before half-time.
The second score is from Springbok World Cup winning prop Ox Nche as he powers over simply from a tap penalty.
Dragons scrum-half Dane Blacker will not want to see that again. Tried to take a quick tap penalty but lost possession of the ball although it was not a knock-on.
Conditions causing problems for both sides.
In France...
Dragons 3-0 Sharks
We will keep you up to date with events in the south-west tip of France.
Not only is new Wales captain Dafydd Jenkins leading Exeter Chiefs but the result will have a direct bearing on who the Ospreys - and perhaps Dragons - face in the last 16.
That's because Bayonne are already guaranteed to be one of the four teams dropping down from the Champions Cup to the knockout stage of the Challenge Cup - along with Connacht, Sale and Ulster.
The question is what order they will be seeded.
If Bayonne win, Ospreys will host Sale in the next round.
If Exeter win, Ospreys face Connacht.
As it stands, Bayonne lead 7-0 after 10 minutes.
Penalty - Dragons 3-0 Sale
Cai Evans
Early pressure from Dragons give Wales squad member Cai Evans the chance to open the scoring with a penalty.
Post update
Dragons 0-0 Sharks
It is a big eight days for Dragons and Newport County football team who share the Rodney Parade ground.
Newport beat Wrexham 1-0 yesterday and will host the mighty Manchester United in the FA Cup fourth round next Sunday.

What a turnaround.
Converted try: Dragons 6-7 Sharks
Jaden Hendrikse (con Curwin Bosch)
The pressure has eventually told and it is scrum-half Jaden Hendrikse who is the beneficiary after the power of the Sharks forwards.
Sharks take the lead for the first time.
Post update
Dragons 6-0 Sharks
The wind is causing havoc and a kick from Sharks fly-half Bosch has gone dead and given the Dragons an attacking opportunity but nothing comes of it.
Post update
Dragons 6-0 Sharks
The weather is very different back in sunny South Africa and the Sharks players look like they are struggling in the windy and wet Welsh conditions.
They will hope they settle down soon.
Post update
Dragons 6-0 Sharks
Wales Under-20s captain Ryan Woodman is a great prospect and achieved a crucial turnover for his side there.
One to watch for the future.
Penalty - Dragons 6-0 Sharks
Cai Evans
Dragons might have blown two tries in the same move but have managed a second penalty through Cai Evans to double the lead.
Not bad playing into a strong wind.
Post update
Dragons 3-0 Sharks
After that excitement we are back to a kicking battle at Rodney Parade.
Dragons will wonder whether that Jared Rosser score being ruled out will come back to haunt them.
Drama! No try for Dragons
Dragons 3-0 Sharks
What a period of play and it appeared to be a try for Dragons wing Jared Rosser before he was cruelly denied.
The Dragons were attacking and had a pass intercepted with Sharks clearing their lines which forced Rosser to go back and claim the ball.
He evaded the Sharks defence and burst clear before kicking himself and sprinting away to score.
The conversion was taken but the TMO came in and the officials decided Rosser had not grounded the ball properly!

Not surprising there is an early knock-on by the Sharks in the game. There will be a lot of those tonight!

Adrien Marbot blows his whistle and Sharks' fly-half Curwin Bosch gets us under way at a very soggy Rodney Parade.
