San Francisco 49ers

San Francisco 49ers wide receiver Jauan Jennings (ankle) is being considered day-to-day with an ankle injury heading into the Week 2 matchup with the Minnesota Vikings. Jennings was banged up in the preseason, but he played and led the team in receptions (five) and receiving yards (64) in the win over the New York Jets on Monday Night Football. The team is likely to be careful with Jennings, especially while Brandon Aiyuk knocks off the rust following an offseason hold-in and Ricky Pearsall (chest) recovers from a gunshot wound. Assuming Jennings suits up in Week 2, he's a decent deep-league flex option, but he has a low fantasy football floor.

San Francisco 49ers running back Christian McCaffrey (calf, Achilles) was somewhat of a surprising inactive during Monday's game against the New York Jets. The reigning NFL Offensive Player of the Year was labeled as questionable with a calf and Achilles injury on Saturday's final injury report, but fantasy managers did not know he wouldn't play until the inactives list came out 90 minutes before kickoff on Monday. While McCaffrey's Week 2 status is still up in the air, head coach Kyle Shanahan said he would have played if it was a playoff game, which means his aliment could be manageable. The team is likely to be careful with McCaffrey early in the 2024 campaign, so Jordan Mason could be on the fantasy radar even when CMC returns to action.UPDATE: Shanahan says that McCaffrey will be "day-to-day" this week.

San Francisco 49ers fullback Kyle Juszczyk hauled in two of his three targets for 40 yards in the team's Week 1 win over the Jets. Juszczyk was on the field for 40 snaps and ran 17 routes. The versatile back made the most of his three targets in the absence of Christian McCaffrey. However, he did not see any carries out of the backfield. Despite being a fullback, Juszczyk operates as a second tight end in a lot of ways. Until he sees more targets, though, he is not a fantasy-relevant player. He's a great weapon for a loaded 49ers offense and creates mismatches on the field but he just doesn't get the volume necessary for fantasy purposes.

San Francisco 49ers tight end George Kittle provided fantasy managers with modest production in the team's 32-19 home-opening victory against the New York Jets. The colorful 30-year-old finished the night in a three-way tie for the team lead in targets with five, which he parlayed into four receptions for 40 yards. In recent memory, Kittle has been the quintessential boom/bust fantasy asset at a boom/bust position but still managed to finish as the TE5 in half-PPR scoring last season. He surely has better -- and worse -- weeks coming. Fantasy players who drafted the "Tight End University" co-founder should keep rolling him out there until further notice, including in Week 2 when the Niners go to Minnesota to take on the Vikings.

San Francisco 49ers wide receiver Brandon Aiyuk disappointed in Monday night's 32-19 victory over the New York Jets in Santa Clara after spending the preseason seeking an extension and asking to be traded while only participating in team meetings. This led to head coach Kyle Shanahan easing the former Sun Devil into game action and limiting his snaps in Week 1. At times during Monday's matchup, Aiyuk looked less-than-sharp, including dropping a sprawling, but catchable ball in the back corner of the end zone. He finished in a three-way tie with Jauan Jennings and George Kittle for the team target lead with five but only caught two for 28 yards. Time will tell how long it will take for Aiyuk to shake off the rust, but it should be sooner than later that he settles into his usual WR2 value. He'll try to get it going against the Vikings in Minnesota in Week 2.
