Marcus di Rollo's Toulouse are also still in the mix for the title and face London Irish on Saturday - but the injury-plagued Scotland centre is unlikely to break his way into the French club's star-studded backline.
That leaves Ross to represent Scotland, which he will do from the bench in Sarries's clash with Irish province Munster.
Playing understudy to first-choice stand-off Glen Jackson, Ross has been a solid performer when called upon - as he is most weeks by director of rugby Alan Gaffney.
His steady form will not have escaped the attention of Scotland coach Frank Hadden, who left the former Castres and Leeds back out of his 2008 RBS 6 Nations squad.
Indeed the last time Ross played for Scotland was in the country's last victory away from home in the RBS 6 Nations - against Italy in Rome at the end of the 2006 championship.
With the stand-off berth probably the least secure in the Scotland side, the time is ripe for Ross to make an impact.
