You cannot get the protector to evolve Rhydon in Pokemon Red version, because Rhydon's ability to evolve with a protector into Rypherior is only available in the latest versions: Pokemon Diamond, Pearl, and Platinum. It is impossible to even get a protector in Pokemon Red version, let alone evolve Rhydon.
to evolve rhydon you need a protector. I think you can get one on stark mountain. Then you have to give it to Rhydon and trade with a friend.
Rhydon evolves when the "Protector" is held and the Pokemon is traded.
Trade your rhydon while it is holding a "protecter".
