Meanwhile, Fraser McKenzie could be sprung from an Edinburgh-dominated replacements bench to make his 'A' team debut.
With eight Ulster players in the Wolfhounds squad, they will be eager to put one over on the province's winger Simon Danielli, who will line out on the left wing for Scotland 'A', while ex-Ulster centre Rob Dewey is on the visitors' bench.

Pre-Match Quotes: Chris Henry (Ireland Wolfhounds) - "Because it's a short week. there's new lineouts, new calls, new phase calls. A lot of the preparation is organisational, the provinces have their own individual calls so it takes a while to get into it.
"But we are always very well prepared, the management do a great job getting us to the place we need to be for a game.
"We talked about the loose balls we lost at the breakdown (last week against England Saxons), our scrum probably in the first half wasn't as good as it should have been.
"There's a few personnel changes and we've gone through our lineouts, we've done a lot of lineout work and worked on our scrum.
"That's the priority, getting good ball off set pieces to give our backs a chance.
"There's some great talent in the back-line and some serious speed, so hopefully we'll be able to chuck the ball about and it'll be a good game to watch.
"The 'A' team has been successful over the years, and last week was a bit of a blip for us. Now we just want to make sure we get things back on track and beat Scotland."
Sean Lineen (Scotland 'A') - "The players have all bought into what we are trying to achieve and they realise this is a stepping stone towards playing for Scotland in the Six Nations.
"Last year Scotland 'A' enjoyed a huge amount of success, including the Nations Cup triumph in Romania, and only lost one match in 2009.
"Unfortunately that result was against Ireland 'A', so we are keen to set the record straight and produce a positive performance in Belfast.
"All of the players involved are pushing for selection in the senior team and there is the right balance in the squad with youth and experience.
"To have two world-class players like Mike (Blair) and Euan (Murray) gives everyone a massive lift and it promises to be a good night of rugby."
