DiManche was waived by the 49ers on Tuesday, Jim Thomas of the St. Louis Post-Dispatch reports.
DiManche inked a deal with the 49ers about a month ago after playing in just one game with the Browns over the past two seasons. The fact that he's being let go this early in the offseason isn't encouraging about the potential for DiManche to make a regular-season roster, but he'll continue to work out over the summer with the hope of receiving a training camp invite elsewhere.
