Edinburgh stalwart Craig Smith has been called into Scotland’s squad for the summer tour of Argentina in place of injured Glasgow prop Moray Low.Smith, who has made 167 appearances in the black and red over the past eight years, missed the final three matches of the Magners League season with a calf problem. But the 29-year-old prop, who first toured Argentina as part of the Scotland under-19 squad that also included Chris Paterson in 1997, has been given the all-clear to join Frank Hadden’s squad.Smith was named last week in the Scotland A squad for the Barclay’s Churchill Cup in North America next month. A replacement for that squad will be announced later this week.Glasgow centre Max Evans has also been promoted into the squad and Hadden revealed that there is still a question mark over the fitness of Edinburgh winger Simon Webster, who missed the end of the season with a hamstring injury._Scotland coach Frank Hadden said: We have decided to promote Max Evans from the Scotland A squad._ Max has played well in the Magners League for Glasgow and is another to have benefited from involvement with both Scotland A and Scotland 7s. We are still waiting to see if Simon Webster will recover from his hamstring injury to make the tour. Hell be subject to further monitoring and we’d hope to make a decision on Simon next week.
