Honda is planning a private two-day MotoGP test at Jerez late next week for Marc Marquez and Dani Pedrosa.
The factory squad had originally planned on two additional days of testing back at Sepang, but has made a last-minute change to its plans.
With concerns over the Sepang surface and the amount of time it takes to dry after heavy rainfall, Honda has decided Jerez is a safer bet at this time of year.
HRC boss Livio Suppo confirmed that the plan was in the works, but stopped short of saying definitively that the Jerez test will go ahead.
"We haven't made a final decision, but we've rented the circuit," Suppo told Motorsport.com.
It is not known if only Marquez and Pedrosa will take part in the test, or if other Honda riders will also be in attendance.
Each MotoGP rider have five private test days available each year, with both HRC riders yet to use any so far in 2017.
Marquez and Pedrosa were set to take part in a Jerez test late last year, before Honda opted to run Jack Miller and test rider Hiroshi Aoyama instead.
