West Ham striker Jack Jeffery has joined League One club Leyton Orient on a one-month loan.

Jeffrey, 19, enjoyed a promising start to the 2008/09 season, including two goals in this week's 4-0 reserve team friendly win against Norwich.

He was on loan with Cambridge United for the final three months of last season and also had a spell with Hampton & Richmond Borough.

Jeffery could make his Orient debut at home to Stockport County on Saturday.
