Blue Square Premier club Cambridge United have signed striker Calum Willock and defender Kevin Roberts until the end of the season.
Willock, 28, joins on non-contract terms while Roberts, 20, had his contract terminated at troubled Chester City.
U's boss Martin Ling said: "Calum has joined us on a non-contract basis to show us in the short term what he is all about.
"Kevin is a good addition to the squad. With games coming thick and fast, his versatility will be a big asset to us."
Willock (pictured) started his career with Fulham, but made his name with Peterborough in Coca-Cola League One.
Most recently he has been with league rivals Crawley Town and arrives at the Abbey having scored twice in sixteen appearances this season.
Utility-man Roberts has been ever-present for Chester, but settled his contract at the Deva Stadium as a result of the club's ongoing financial problems.
