Blues concede a scrum five after the Dragons pile on the pressure again. Adam Jones and Phil Price are lectured by referee Leighton Hodges and then the Blues claim possession against the head.
Then Jones is replaced by Taufa'ao Filise and Anscombe comes on for Gareth Davies.

There's been plenty of endeavour and strong running from both sides, but it is Dragons who find themselves ahead at half-time.
Blues have struggled to break down Dragons' defence and it's no surprise with tackles like this.

Second half underwaypublished at 15:04 Greenwich Mean Time 26 December 2014
Here we go then. Can the Blues rediscover their home form in the second 40? No replacements during the break.

"Our kicking game has been really poor. We're playing the game in the wrong areas and it's killing us."

A very disappointing first half for the home side. Blues director of rugby Mark Hammett will have plenty to say during the interval.
Half-time: Blues 3-13 Dragonspublished at 14:52 Greenwich Mean Time 26 December 2014
Well, Blues coach Mark Hammett was right when he said the form book would count for nothing. The Dragons have dominated at the breakdown and carried the ball more effectively than their hosts. Gareth Davies' failure with two penalty attempts has further hampered the Blues. Gareth Anscombe is on the bench. Will we see him early in the second half?

No they can't. Rynard Landman steals the ball and Jason Tovey pins the Blues back into their own 22 where they concede a lineout.

Big mistake by Dragons as they put the ball straight out after carrying the ball into their own 22. Can the Blues take advantage?
