Otudeko joins the Stones in time to be in contention play in their league fixture against Truro City on Saturday.
The forward has represented 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.
Otudeko is eligible for the Buildbase FA Trophy quarter-final where Wealdstone will play the winner of tonight`s replay between Bostik League Premier high-flyers Billericay Town and National League North promotion-chasers Harrogate Town.
