Winger is U's second addition.
Colchester United have made their second signing of the day, bringing in wide man Nathan Oduwa on loan for a month from Tottenham Hotspur.
Nathan has been with Spurs from the age of 11 and has been a regular in their U18s and U21s in recent years.
He has twice been out on loan from the Premier League side, spending the back end of the 2014/15 season on loan at Luton, before spending the first half of this campaign in Scotland with Rangers.
Nathan goes straight into Saturday's squad and will wear squad number 30.
He has played for England through to U20s level and is predominantly a left winger.
