Geoff Cross, who will be thrown into Scotland's Six Nations clash with Ireland on Sunday, will be hoping to stake his claim for front-row spot with by impressing coach Scott Johnson as he deputises for Euan Murray this weekend.
Committed Christian Murray is unavailable to play on Sundays, and Cross is set to take the tighthead prop's spot at Murrayfield as the Scots look to build on their defeat of Italy a fortnight ago.
And the 30-year-old Cross, who is a qualified doctor, is certainly worth keeping an eye on this weekend.
He has found himself behind Murray in the pecking order for most of his career and so will be desperate to impress Johnson as he is given a rare starting berth.
Johnson has not started a match for Scotland since scoring his first Test try in November's comprehensive 22-51 defeat by the All Blacks and has declared that Sunday represents his chance to show Johnson "this is why you should pick me".
The Ireland showdown is Scotland's only 2013 Six Nations fixture taking place on a Sunday, so if Johnson is to oust Murray for the clashes against Wales and France, he will have to do so on merit, starting with a stellar display this weekend.
