Buthelezi, who made such an impressive hurdling debut at Aintree in December, will be out again at the end of the month.
A smart horse on the level for John Gosden, he finished seventh in the 2011 St Leger and subsequently joined John Ferguson for a new career.
Sent off at 4-1 on his first start over timber, he made every yard of the running against some decent rivals and held an entry in the Tolworth Hurdle.
Ferguson said: "I decided not to run Buthelezi at Sandown (Tolworth). He's coming along perfectly well and has done very nicely since his win.
"He'll hopefully be out somewhere at the end of the month although I haven't got a race in mind yet."
