Rochdale boss Keith Hill looks certain to be without Will Buckley for the home clash with Port Vale.

The highly-rated winger sustained a thigh strain during the warm-up to Saturday's 4-1 win at Cheltenham.

He was replaced in the starting line-up by Blackburn winger Andy Haworth, who made his debut following his loan move to Spotland.

Haworth impressed for the League Two leaders and is now set to make his home bow, but Manchester United goalkeeper Tom Heaton's loan expired after Saturday's win.

First-choice stopper Kenny Arthur is fit again and could return between the posts if Dale choose not to extend Heaton's loan spell.

Hill has no other major concerns as his side seek extend their lead at the summit.

Port Vale will continue to assess Sean Rigg in the build up to the clash.

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.
