The Spanish centre-back has fallen down the pecking order at Carrow Road, and he spent a loan spell with Nottingham Forest last season.
According to the Derby Telegraph, the 22-year-old will now move to the Riverside Stadium until January.
It has also been reported that Middlesbrough have the option to sign Ayala on a permanent basis at the conclusion of the loan period.
