Colchester have signed midfielder David Prutton on a month's loan from League One rivals Leeds.
Prutton, however, will be ineligible for the trip to Elland Road at the weekend because of the terms of the deal.
"I am pleased to be bringing in an experienced player who has been at a much higher level in his career," Colchester manager Aidy Boothroyd told the club's official website.
He added: "David will bolster our central midfield area for the games to come."
