It will be the 20-year-old’s second spell with the Rebels having previously joined on loan in similar circumstances in the 2020/21 season when Roco Rees was injured.
The shot-stopper is formerly of Brighton & Hove Albion, representing the Seagulls’ age-group sides up to the U23s. Bull has represented Republic of Ireland at U19 level and has also spent time at Eastbourne Town, Carshalton Athletic, Aveley and most recently Wealdstone this season.
Bull’s signing follows news that on-loan Southampton goalkeeper Ollie Wright suffered a knee injury this week that will keep him sidelined for a short period.
Toby’s signing was completed in time for the keeper to be available for selection this afternoon as the Rebels take on Taunton Town in the National League South.
