Roberts returns for Cardiff Blues

Cardiff Blues coach David Young brings back Jaimie Roberts and three others for the clash with Ulster in the Magner's League tomorrow.

Centre Roberts comes in for the injured Tom Shanklin. Up front, Sam Warburton starts at openside, Maama Molitika at blindside and Deiniol Jones returns from injury to start in the second row.

Coach Young said: "We were not happy with the way we played last week but at the end of the day it was a win so we have to be pleased with that and as I said after the match the result is a lot more important that the performance at this stage of the season."

"We can play a lot better but we also expect them to be a lot better. If we can get the result it will certainly help our cause."

"We obviously struggled last week as we had a number of players coming back into the team after Welsh duty and it looked as if they hadn't played together for a number of weeks which was the case so we will be looking for a big improvement this week."
