If neither are fit the dependable Paul Rudd is likely to step up to second row which means that new signing Ed Britton could be in the back row with Stu Bennett and Tim Sawyer.
Britton came on as a replacement last week and performed well as did his University colleague Tom Rance on the left wing.
Phil Gilbraith is also knocking on the door, and Stabler could decide to start with Bennett on the bench to give youth its head for the first hour of the game.
The rest of the side picks itself and will have to put in a full 80 minutes if we are to get a result against third placed Chester.
They are only two points behind leaders Cleckheaton who surprisingly lost heavily at Macclesfield last week. Rumour has it that they've lost a couple of key players with the start of the Rugby League season - next week Cleckie visit us!
But first its Chester. They also lost away last to Hertford in the cup in front of a frowd of 1,000 which suggests their hosts may be one of the clubs to watch for in the next few seasons.
West Likely line up: Darren Thomas, Tommy Barff, Jamie Connolly, Allan Milne, Tom Rance, John Stabler, Davy Tighe, John Painter [capt], Brett Cullinane, Carl Robinson, Paul Rudd, Andrew Davies, Ed Britton, Tim Sawyer, Stu Bennett.
