The 21-year-old Jonas Brothers' star, who has earlier appeared in TV series such as 'Hawaii Five-O' and 'Smash' will be playing Nate Henderson, a shy kid, who receives a mixed martial arts fighter in contract in the show, said The Hollywood Reporter.
'Navy St' is set against the backdrop of a mixed martial arts gym in Venice, California, named Navy Street run by Alvey Henderson, a former fighter whose drug addiction prevented him from making it big.
Sanchez will play Lisa Prince, Alvey's long-time girlfriend.
