Tume, who joined Southampton-based Sholing from Sutton United in the summer, penned a new deal in November following a bright start at the club.
The 19 year old has already featured at League Two level, having made two appearances from the bench in the division during his time at Sutton.
He spent last season on loan at step four club South Park before reuniting with former Sutton under-18s boss Ross White at Sholing.
Tume was named on the bench for Sholing’s 0-0 draw at Evesham United on Saturday. That result leaves the Boatmen fifth in the Southern League Premier South.
