This is a bummer for the team and fantasy purposes, as this impacts the playoff implications for both facets. If you don't have an IR spot, it may be a waste of a spot for Deebo if he isn't going to return before Week 17.
SF WR Jauan Jennings - Week 16 Fantasy Football Outlook
Week 16 at Tennessee Titans
Jauan Jennings had a touchdown last week, which is nice, but what is most intriguing is his target-share the last two weeks. He has 11 targets in the past two games, and was looked to far more often than Brandon Aiyuk was against the Falcons. That may not translate into production, but he’s worth an end-of-roster spot on your bench in case this continues going into the final weeks of the season.
