It's a landmark day for Blues loose-head prop Sam Hobbs who makes his 100th appearance for the region.

He takes over from Gethin Jenkins - who has made more than 100 international appearances for Wales.

Dragons director of rugby Lyn Jones is getting all Bob the Builder - or is it President Obama?

"There were a lot of records made by Newport Gwent Dragons in the first two years of regional rugby. Since then they have been putting some negative records together.

"My job here is to help turn those things around and one of which is it would be nice for us to go to the Arms Park and win. Can we do it? Yes we can. Are we good enough? Yes we are. Are we confident? Yeah we are!"

Dragons centre Tyler Morgan plays for the region for the first time since being injured in September fresh from signing a WRU dual contract.

The 19-year-old is the first uncapped player to sign one of the new contracts, and was thrilled with the news.

"I'm a local boy and I'm very happy at the Dragons, so I'm delighted to commit my future to them and to Welsh rugby," he said.

"The contracts allow us to work closely with the national squad management and for me that was a big incentive.

"Being able to get that extra advice and guidance will really benefit me going forward."

Morgan's Dragons team-mate Hallam Amos also has also signed a dual contract today.

What do you think? Will it be a Christmas cracker or has one team eaten a little too much Christmas pudding this year?

Let us know. Kick off is just six minutes away...

Blues director of rugby Mark Hammett is not relying on the form book - which suggests the Blues will win.

"When you have derby games you have to be careful about looking at past form and strengths and weaknesses," said the New Zealander.

"Derby games bring out a greater intensity and a competition which can be different. Often it's the attitude that wins these games over technique and tactical nous.

"It's a massive game and very close to being sold out. It's critical that we perform at home in front of the supportive crowd."

And in the pantomime season, here are some "villains" you might want to jeer - all in good fun, of course!

Prynhawn da and Nadolig Llawen! Welcome to the traditional festive Welsh rugby derby.

And after charades and Candy Crush Saga (other computer games are available) on Christmas Day, it's time to get down to a serious game on Boxing Day.

It's Blues v Dragons at Cardiff Arms Park with Pro12 points and local bragging rights at stake.

The team from Newport have not won in Cardiff since 2003, so with only five points between them in the table, a long-overdue win for the visitors could close the gap to a point - or even put them on level terms with a bonus point.

Now that would be a Christmas bonus.
