Vale boss waits on Rigg fitness

The on-loan striker missed the goalless draw against Macclesfield with a hamstring injury and is again doubtful.Striker Geoff Horsfield has also been struggling with a hamstring problem and it remains to be seen whether or not he will be fit enough to feature.Boss Micky Adams also has a decision to make over which formation to use at Spotland.A 4-4-2 formation has proved effective in recent games, but with Rochdale posing a big attacking threat, he could switch back to a more defensive system.If he opts for the latter centre-back John McCombe is likely to be recalled to play in defence.
