Huff was optioned to Triple-A Round Rock on Sunday, Kennedi Landry of MLB.com reports.
Huff served as depth behind the plate while Jonah Heim was on the paternity list, but he'll head back to the minors since the Rangers need to trim their active roster to 26 players by Monday. Heim will operate as the team's No. 2 catcher after he was activated Sunday.
