San Francisco 49ers

With Christian McCaffrey receiving a training-camp rest day on Monday, Jordan Mason was the San Francisco 49ers' first running back on the field for the start of team drills. Mason, the 49ers' No. 3 back the past two seasons, carried the ball on the first snap. Elijah Mitchell, the No. 2 back sinceMcCaffrey arrived in 2022, had a carry on the second snap. Head coach Kyle Shanahan also shared praise of Mason's development after the session. After Mitchell served as McCaffrey's unquestioned backup, Mason at least is making the situation murkier.San Fran's backfield pecking order behind McCaffrey will certainly be something for fantasy managers to monitor leading into the Aug. 10 preseason opener against the hosting Tennessee Titans. Until then, Mitchell should be treated as CMC's preferred handcuff at the end of fantasy drafts with rookie Isaac Guerendo (hamstring) sidelined.

San Francisco 49ers running back Isaac Guerendo (hamstring) is dealing with a significant hamstring strain and will be out for a few weeks, according to head coach Kyle Shanahan. It's a tough development for the fourth-round rookie from Louisville, who will miss valuable reps as he looks to compete for the RB2 job behind Christian McCaffrey. Guerendo was widely unknown heading into the pre-draft process, but his 4.33 40-yard dash time at the NFL Combine raised eyebrows and got him selected at the start of Day 3 of the 2024 NFL Draft. While his injury could slow down his development and chances to make an impact early in his career, he remains an intriguing late-round flier in deep fantasy football leagues.

San Francisco 49ers head coach Kyle Shanahan reported that Saturday brought no news on the team's star wide receiver Brandon Aiyuk's current hold-in. Shanahan also stated there was no update on Trent Williams' holdout. Aiyuk requested a trade earlier this month and is lobbying his team for a new deal. He reported to training camp on time but is not practicing until his contract situation is resolved. The fifth-year wideout was integral to the 49ers' run last season as he enjoyed his full-on breakout. It is possible that Aiyuk will be traded according to his request, but San Francisco has drawn these situations out in the past, and he likely plays this year in 49ers red. Regardless of where he plays, the Arizona State product has cemented himself as an upper-echelon receiver for fantasy. He's currently the WR16 in NFFC ADP (29th overall), and that's a good spot for him in drafts despite the hold-in.
