Dagenham & Redbridge midfielder George Porter has signed a new deal with the club until February.
The 22-year-old joined the League Two side at the start of the season after impressing during a trial spell.
His previous terms were due to expire before the end of the month, but the Daggers have now tied him down to a fresh contract.
Porter has scored two goals in 22 games for Dagenham so far this season.
