On the top-of-the-table clash Blackadder said: "This is a great opportunity against the front runners in the Celtic League. We've had a good break and the players have come back refreshed. We needed that mentally as well as physically and we are all ready to go out there with a lot of enthusiasm.
"We picked up five points from our game against the Reivers but we knew our match against Munster was coming up. They are top of the league but we will be playing at home. We've had a good start to the Celtic League season and that is something that we should be really proud of. We've got a good strong, quality side," he added.
Webster received intensive rehabilitation over the festive period and it is hoped that he will return to training next week. Jacobsen had a scan on his knee and will be treated by the Gunners' medical team over the coming week.
