No need to worry. Depending on it being in the groin or up higher, it can be a bit more invasive to remove during the neuter surgery.
In addition to what Renee said, please make sure your breeder knows (if he/she wasn't already aware of this). It's a genetic component that the breeder should be aware of for future breeding decisions.
Also, sometimes people consider skipping the neuter, but I believe that a retained testicle presents a much higher rate of testicular cancer.
