Breida did not play any snaps on offense in Saturday's 34-31 win over the Rams.
The oft-injured back was not listed on the injury report, so his demotion to special teams was a coaching decision. Breida had a rough go of it last week against Atlanta (four carries for 11 yards and a lost fumble), which may have played a role in his lack of touches. The speedy back has otherwise been solid when deployed this season (119 rushes for 607 yards and a touchdown), so coach Kyle Shanahan may also be attempting to keep Breida fresh for the playoffs after the third-year back endured multiple injuries over the course of the regular season. Sunday's matchup against Seattle will decide the fate of the NFC West, so while the 24-year-old could be part of the gameplan, the uncertainty surrounding his playing time makes him tough to trust for fantasy purposes.
