Monitor the health of both starting quarterbacks: Jimmy Garoppolo suffered a season-ending foot injury, while Tua Tagovailoa suffered an ankle injury at the end of the game.

• Seventh-round rookie Brock Purdy took over as the 49ers' starting quarterback. Jacob Eason is on the team's practice squad and will likely serve as the backup going forward.
• Purdy’s average depth of target was a little lower than Garoppolo's, and he took slightly longer to throw the ball on average. 
• This likely means more targets for Christian McCaffrey and Deebo Samuel and fewer for Brandon Aiyuk and George Kittle in the future.
• The 49ers have a relatively comfortable three-game stretch before a favorable Week 17 matchup against the Raiders.
• Purdy isn’t necessarily someone I’d look to pick up outside of superflex leagues.
• At present, not much is known about Tagovailoa’s injury. 
• Skylar Thompson went in for Tagovailoa and immediately threw an interception. Teddy Bridgewater would probably take over if the injury is serious, but Bridgewater was inactive with a knee injury today.
• Reports after the game are that the injury probably isn’t serious.

Christian McCaffrey dominates snaps: Some fantasy managers have been concerned about his usage recently, but that wasn’t a problem this week against the Dolphins.

• McCaffrey dominated snaps early on, with Jordan Mason working in slowly but surely as the game progressed.
• Elijah Mitchell had served as the backup in recent weeks, but he is on injured reserve.
• McCaffrey led the team in both rushing yards and receiving yards.
• Now that the 49ers will be relying on a rookie at quarterback, they are less likely to have large leads where they might take McCaffrey out.
• Unfortunately, it also means they are less likely to be in a position to get him touchdowns. He will remain a top-10 running back over the rest of the season, but it will be harder for him to finish top-three.

The Dolphins make a change at running back: Raheem Mostert dominated touches in the Dolphins backfield, even though Jeff Wilson had received more touches in recent weeks.

• Mostert ran the ball seven times compared to one by Wilson.
• Mostert started the game as he has in every game he played since Week 4.
• He missed last week with an injury, and Wilson averaged only 3.0 yards per carry in that time.
• His poor play last week may have been enough for the Dolphins to lean more into Mostert than Wilson this week.
• Wilson dropped a pass in this game, adding to the recent string of poor play.
• The 49ers dominated the time of possession, keeping the ball for over two-thirds of the game. It’s possible Wilson would have played a higher percentage of snaps if the Dolphins had run more plays.
• Mostert is probably the safer of the two backs to roster going forward. 
• Miami plays the Chargers next week, and they’ve allowed the second-most fantasy points to running backs. It’s possible one or both running backs could be a fantasy starter next week.

Monitor the health of Jaylen Waddle: Waddle left at the start of the third quarter with a leg injury. He returned later in the quarter but played only a few snaps over the rest of the game.

• River Cracraft was the biggest beneficiary in snaps rather than Cedrick Wilson. Wilson signed a big free-agent contract with Miami this offseason but hasn’t made much of an impact.
• Trent Sherfield has been the Dolphins' third receiver all season. He scored a 75-yard touchdown on the first offensive play but didn’t have a catch over the rest of the game.
• Sherfield would be worth a waiver wire target if we find out the Waddle injury is serious.

Table Notes

• Snaps include plays called back due to penalties, including offensive holding or defensive pass interference. The other three stats have these plays removed.

• Targets may differ from official NFL sources. The most likely discrepancy would be from a clear thrown-away pass, where the NFL may give the target to the nearest receiver, while this data will not.

• Carries are only on designed plays. Quarterback scrambles won’t count for the total number of carries in the game.
