The Ballymena man gets the chance after David Humphreys suffered ligament damage to his left arm against Leinster and with Ireland’s opening Six Nations game a month away Wallace could also nail down a place in Eddie O’Sullivan’s squad.
Wallace has learned a lot being understudy to Humphreys but he now feels is time he pushes on and establishes himself as first choice out half.
He said: “David has been a world class player for the last eight to ten years and you don’t get over 70 Irish caps if you’re a bad player. I’ve picked up a lot of help from him but I’m now 27 years old and at this stage of my career I’d like a bit more time at 10. I want to do the shirt justice as it has been in good hands over the last few years.”
