It's now extremely tight at the bottom, with Dunfermline now back to being a point behind Saints, with Motherwell just a further four points up the road. The game also means both sides are without key players for Saturday due to suspension.
Dunfermline will be without captain Scott Wilson for their trip to Inverness Caley Thistle, while Motherwell will be without Mark Reynolds and - more importantly - Scott McDonald for the visit of Saints.
It's all getting very exciting and close - look out for Mirren Mad's indepth look at the relegation battle later in the week.
