The free agent infielder and outfielder did not provide a timetable for his return.
Hernández wrote on Instagram that he'd been playing hurt for about a month with the Los Angeles Dodgers when he went on the injured list with left elbow inflammation July 7. He returned on Aug. 26 but was limited to 93 games.
He had 16 postseason hits in helping the Dodgers win their second consecutive World Series title and his third with the club. He hit .203 with 10 homers and 35 RBIs during the regular season.
