Kettering Town have signed Peterborough youngsters Nathan Ralph and Danny Mills to bolster their depleted squad.
The club are under a transfer embargo but BBC Radio Northampton understands that teams can add players when they are low on registered players.
Manager Mark Cooper told BBC Radio Northampton: "We were allowed to sign youth players that would cost no money and we're allowed to sign one more.
"Ideally, we need a defender, but we couldn't get one in time."
He continued: "We'll have to make do. The new boys will take part tomorrow."
Striker Mills, 20, was with the Poppies under previous manager Marcus Law, and joins until the end of the season on a youth loan.
He started his career at Crawley and has had loan spells with Torquay, Rushden, Histon and Tamworth since his move to Peterborough.
Ralph is an adaptable, left-sided 18-year-old and joins on work experience.
"Danny was there when I was manager at Peterborough," Cooper said. "I've seen Nathan a couple of times in the reserve and youth teams. They're both exciting players."
The pair are available for the Blue Square Bet Premier match against Forest Green Rovers on Saturday.
