Both teams are fresh from strong wins in the Magners League last weekend, the Blues with a 39-16 win over Scarlets away in Llanelli and Dragons with a 49-28 win over Edinburgh.
The Blues put five tries past Dragons when they visited the Cardiff City Stadium before Christmas, but very little seperates the teams now and the match looks to be a great spectacle for both sets of fans.
Speaking ahead of the game, Dragons head coach Paul Turner said;
"The Blues are the form side in the Magners League and there's no doubt that their players will be bringing their A game to Rodney Parade.
"They will be wary of us, but also confident as they look to their Amlin Cup match next week. But we are continuing to move in the right direction and our supporters have been key to our success."
Dragons 24 man squad;
Martyn Thomas, Will Harries, Rhodri Gomer-Davies, Tom Riley, Ashley Smith, Richard Fussell, James Arlidge, Shaun Connor, Jason Tovey, Alex Walker, Wayne Evans
