Ulster confidence to show
THIS contest could have a massive knock-on effect for the Heineken Cup campaigns of both clubs given their relative health in their respective Pools.
The last thing coaches Michael Bradley and Brian McLaughlin need is a bump in the road the week before the most important match of the season, thus far.
"Like us, Ulster have so far enjoyed a successful Heineken Cup campaign but have not been as convincing in the PRO12," said Edinburgh boss Bradley.
"We have shown good form in front of our home support, winning six of our last seven at Murrayfield.
"However, Ulster have lost just one in their last five so will arrive with a lot of confidence."
