Saubert was released by the 49ers on Tuesday.
Saubert inked a deal with the 49ers in April and was expected to primarily serve as a reserve blocking tight end. The 30-year-old made a push for a spot on the roster this preseason, but the team will instead roll with Jake Tonges as its lone backup behind starter George Kittle. Across 10 regular-season appearances with the Texans and Cowboys last season, Saubert caught three passes for 12 yards and worked mostly as a special-teamer.
