The 18-year-old striker has joined the Glovers on a month’s loan from Premier League side West Bromwich Albion.
Manager Darren Way said: “We have been keeping an eye on Tahvon at West Brom for a while now. I have watched him play a number of times and he is everything we are looking for in a striker.
“This club has a great record of having young players on loan, who have great prospects and Tahvon certainly fits into that and fingers crossed he gets good game time with us here at Huish Park.”
Tahvon will go straight into today’s squad to face York City and will wear the number 16 during his stay at Huish Park.
