Oteduko is a versatile forward that manager Tom Killick has seen play and he liked what he saw.
The forward has represented the Bristol Rovers development squad on a number of occasions this season and made the bench for the first-team during the Checkatrade Trophy fixture against Wycombe Wanderers at Adams Park.
The former Watford youth player spent last month on loan at fellow National League South side Wealdstone.
He goes into the squad for Saturday's away game against table-topping Dartford.
