Darlington have struck a deal with Colchester to keep goalkeeper Dean Gerken for a second month.
Gerken joined the Quakers on an initial one-month loan deal in January and he has proved to be an accomplished performer, conceding just two goals in four games.
Colchester manager Paul Lambert is happy for the 23-year-old to stay with Darlington until the middle of March, although there is a 24-hour release clause in the deal
"Dean is doing just fine up there and he will be staying for at least another month," Lambert told Colchester's official webite.
"We've got Jimmy (Walker) here at the moment and being at Darlington gets Dean games."
