Prop forward Geoff Cross has been called up into the Scotland side for Sunday's Six Nations international against Ireland at Murrayfield in the only change to the side that beat Italy earlier this month.
Euan Murray, following in the footsteps of Scotland rugby and athletics great Eric Liddell and New Zealand's 1987 World Cup-winner Michael Jones, refuses to play on Sundays because of his Christian beliefs.
And that led Scotland's Australian interim head coach, Scott Johnson, to select Edinburgh front-row Cross in Murray's place at tight-head prop on Wednesday in the only change to the side that defeated Italy 34-10 at Murrayfield last time out.
Cross will be looking to follow-on from his try-scoring exploits against world champions New Zealand when he last started for his country.
Scotland head into the weekend's third round of Six Nations matches second behind unbeaten leaders England.
Ireland, fourth in the standings, were due to name their side later on Wednesday.
