While the Falcons worry about their dismal Premiership start, Murray has been restored to the Scotland front row for the must-win clash with the Auld Enemy, England, on Saturday.
The 31-year-old missed their agonising 13-12 reverse against Argentina as he doesnâ€™t play on Sundayâ€™s due to his religious beliefs.
Widely accepted as the best scrummager in the Scotland pack, Murrayâ€™s inclusion was a no-brainer for coach Andy Robinson after his front-row endured a tough time against the uncompromising Pumas.
With the Scots lacking the creative flair of their rivals, Murray and co. will favour an arm wrestle up front rather than a feast of flowing rugby in Eden Park on Saturday.
And with that in mind 70-cap Scotland winger Logan believes the return of Murray could see the Falcons denied his services for a little while longer with the quarter-final berth, a win could bag them.
A win with an eight-point margin would all-but guarantee them a spot in the knock-out phases and Logan said: â€œEuan Murray back is really important for such a big game against England and for what is going to be a really difficult game.
â€œHis religion and his beliefs are something that you have got to respect but at the same time I think the fans will like to see him back and the England guys will know how good a scrummager he is.
â€œHeâ€™s played against Georgia and really dominated them and they are a really good scrummaging pack so itâ€™s great to have him back.
â€œPeople like Euan can really make a big impact to the team in what is going to be a big game.â€
If Murray and co. fails in their England victory quest they will become an unwanted statistic in the annals of Scottish history – the first side ever to fail to make it out of the pool stages.
But Logan believes the Newcastle tight-head can make sure the unthinkable doesnâ€™t occur, adding: â€œHe is the sort of player that can make those big tackles and have a huge influence on the scrum and put a lot of pressure on England and that is what we will need to do because it is going to be a very hard game.â€
