Dartford's Jon Wallis could be out for the rest of the season with a serious ankle injury.

The former Gillingham and Dover midfielder (pictured) limped off during the 6-1 Blue Square Bet South home win against Sutton last month and Burman feared it would be bad news.

He said: "We were waiting on more news about Jon but the scan has revealed a small fracture in the ankle bone.

"He could be out for three to four weeks which will be a massive blow."

Burman is also facing up to a goalkeeping injury crisis, after the league refused to sanction an emergency loan signing as cover for Louis Wells.

Dartford face rivals Chelmsford at home on Saturday (3pm) before travelling to Bromley on Easter Monday.

Burman added: "Two games in three days always makes it a crucial part of the season.

"Chelmsford are a good side but they will be missing one or two through suspension and that’s why you need strong squads at this stage."
