San Francisco 49ers running back Christian McCaffrey (back) popped up on the injury report on Saturday due to a back issue. According to Adam Schefter, McCaffrey is expected to suit up for the Week 15 matchup against the Tennessee Titans. This issue doesn't appear to be severe enough to keep McCaffrey on the sideline. If he suffers a setback, Brian Robinson Jr. and Isaac Guerendo would likely split up a majority of the snaps in the backfield. Fantasy managers should expect McCaffrey out there on Sunday, but there probably won't be official word until closer to kickoff. The 49ers don't play until 4:25 pm ET, so his official announcement might not be made until sometime in the afternoon.

San Francisco 49ers wide receiver Brandon Aiyuk (knee) was placed on the reserve/left squad list on Saturday. This move will make Aiyuk ineligible to return and will end his season. Aiyuk has been out all season while recovering from ACL and MCL tears in his right knee, which he suffered during the 2024 season. All signs are pointing to the two sides splitting apart this offseason. The 27-year-old should draw interest on the free agent market, but he's likely taken his last snap in San Francisco. Aiyuk is worth stashing in dynasty formats, but it's unclear how this knee injury is going to impact his performance on the field in the future. He can safely be dropped in all redraft formats with his 2025 season being officially over.

Miami Dolphins tight end Darren Waller flashed enough upside in the early part of the season to get some attention, but he hasn't been as involved since returning from IR in Week 13. He and the Dolphins are taking on the Steelers on Monday Night Football, and he can be a deep-league flier if you're desperate at the position. Waller played only 47% and 37% of snaps in his two games since returning and has only had three catches on six targets for 60 yards in the two games combined. He and Tua Tagovailoa showed a decent connection early in the season, especially near the end zone, as Waller scored four touchdowns in his first three games. Since then, though, he hasn't gotten back into the end zone, and his reduced role makes him very hard to trust as a starter in standard-sized leagues. He's ranked as the No. 22 TE in RotoBaller's rankings for this week, even though he's in a positive matchup aginst the Steelers, who have been generous to tight ends. While he does have touchdown-dependent upside, there are better options likely available in most leagues this week.

Miami Dolphins wide receiver Malik Washington has flashed some play-making ability and upside this season, but he is not getting enough downfield chances to be a strong fantasy play this week against the Steelers. The Dolphins are relying on their run game, led by De'Von Achane, and their defense to win them games lately, leaving Washington without much production. He does have multiple catches in every game this season and 10 catches on 12 targets over the last three contests, but he is averaging only eight yards per catch and hasn't reached 50 yards in any game he has played this season. He has two touchdowns this season, but unless the Dolphins open the offense or Washington gets into the end zone, he'll have a hard time putting up enough fantasy points to be a good flex play in Week 15 against Pittsburgh, even though the Steelers have been a good matchup for receivers. Washington is RotoBaller's No. 62 WR in Week 15, so he's safely left on the bench or waiver wire in most formats this week.
