Josh Payne has joined League One club Wycombe Wanderers on loan.
The agreement, initially for a month, will see the 19-year-old midfielder join Wycombe's battle to stave off relegation to League Two. The Buckinghamshire side sit 23rd in the standings, seven points from safety.
Payne could make his Chairboys debut in Saturday's fixture with Southend United at Roots Hall.
Wycombe have failed to win in their last seven league matches, a run stretching back to a 2-1 victory over Stockport County on 5 December.
The teenager, who started West Ham United's 3-1 Carling Cup win over Millwall in August, enjoyed a loan spell with League One outfit Colchester United earlier this season. Last term, he also spent three months with Cheltenham Town, making 13 appearances for the Robins.
Meanwhile, Andrea Zola has joined Blue Square Premier club Grays Athletic for a month, where he will be managed by former Hammers defender Julian Dicks.
The 18-year-old, who can operate at left-back or in a defensive midfield role, has made three appearances for West Ham's reserve team this season.
