Mossy come in at 12 for Allan Milne who trained last night but had to own up to still feeling twinges in his hamstring.
Greg Edwards comes into the back row in place of skipper Tim Sawyer who is recovering from his knee op. Stu Bennett who will be at Number 8 after recovering from his rib injury. The in-form Henry Tones will make up the back row.
Carlo Robinson is working, so Gez Geritz starts alongaside Brett and Anth Carr - but you can bet your boots that John Painter will make an appearance at some point.
Young Phil Butler, who has also been doing great things for the Stags, will be on the bench alongside Darren Thomas who is the unluckiest of a group of "regular" first teamers not to make the starting line up.
But, with a good crop of youngsters, its in the club's interest to keep everyone on their toes and Moss gets his chance at what he says is favourite position. With him and Greg in the side, alongside Wallis, Todd, Carr and Miller this must be one of the youngest sides West have ever fielded. Good job Painter is on the becnh to balance it out!
It won't be easy against Northern. they have only won once - against Bridlington - but their defeats have not been too heavy. They lack a big pack but have pace and flair in the backs and it promises to be a hard but entertaining game.
