Plymouth midfielder Luke Summerfield will stay with Leyton Orient for another month.
The 21-year-old has been handed an extension to his current loan deal at Brisbane Road after five successful appearances for the League One club.
The Pilgrims have found life in the Championship tough this term but boss Paul Sturrock is yet to call upon his loaned players.
He has, instead, afforded Summerfield an additional six appearances for Orient, who have won three of their last four domestic games.
Summerfield will be available for the Johnstone's Paint Trophy tie with Hereford in the coming weeks, but will be ineligible for the FA Cup.
