Up front, there is a more experienced flavour to Doak's selection. Bryan Young, Andy Kyriacou and Dan Tuohy, who all featured for Ireland 'A' against Tonga last week, will start along with fit-again flanker David Pollock.
Ian Humphreys, another 'A' international and Ulster's top scorer in this season's Magners League, could feature off the bench.
In a late change to the bench, Thomas Anderson has been withdrawn as a precaution due to a knee injury, with Chris Henry stepping in for him.
Looking forward to the challenge of the British & Irish Cup, Ravens captain Whitten said: "Being captain just adds that little bit of intensity to the game. I captained Queen's in my third year at University, that was a couple of years ago, so it was a bit of a surprise really when I was asked to be captain.
"I have done it before and enjoyed the experience, so I will make the most of it and try and do my best.
"The Blues are a good side, make no mistake about that. They play a good brand of rugby, and like to move the ball to the touchlines.
"They have quality half-backs, so we have got to be aware of what they can do and try and stop them from playing rugby, then hopefully we can play a bit ourselves.
"Our intention is to win every game, I think that with there being such a big break at this time of the season it is important to give the boys some game-time.
"We need to hit the ground running for the beginning of December, so it is important that the boys stay sharp and it's important that we win on Friday night."
