“Daniel is a legacy at our club as our first player signed and will be remembered fondly for that," Nashville general manager Mike Jacobs said in a release.
"He is a part of the club’s history, and we wish him and his family the very best in this new opportunity in Charlotte."
Rios is originally a product of Chivas Guadalajara's youth academy before going on to feature for USL side North Carolina FC on loan.
The defender gives Charlotte FC head coach Miguel Angel Ramirez another option through the center, alongside DP Karol Swiderski and Vinicius Mello.
