Billy Smith is threatening more changes in a bid to boost Crawley's faltering promotion challenge at home to Cambridge in the Dr Martens premier division.

Marc Pullan is poised to make his first start since the end of November after recovering from a knee operation.

He will partner Ben Judge in the centre of defence because Lee Doherty starts a four-match ban with Keith Sharman likely to be pushed into midfield.

Smith doesn't know whether winger Younis Nabil will be available after he had to rush home to Morocco because his mother is seriously ill.

On-loan Gez Murphy will again partner Ben Abbey up front while Stewart Holmes is available after serving a one-match ban.
