Christian McCaffrey Injury Update
McCaffrey (calf) exited during the second half of last Sunday's game against the Commanders and did not return. With San Francisco guaranteed the NFC's No. 1 seed, McCaffrey will sit out this week's season finale versus Los Angeles but should be good for the playoffs. Elijah Mitchell will draw the start in his place, ranking as an RB3 for fantasy purposes.
Alvin Kamara Injury Update
Kamara (ankle) exited during the second half of Sunday's game against the Buccaneers and did not return. It's currently unclear whether he'll suit up in Week 18. If he can't play, Jamaal Williams would start in his place, ranking as a high-end fantasy RB3.
Najee Harris Injury Update
Harris (knee) was a limited participant during Tuesday's practice. Given that the Steelers' Week 18 game against Baltimore is still several days away, the talented running back should be able to suit up, ranking as an RB3 in most fantasy leagues.
AJ Dillon Injury Update
Dillon (shoulder) exited with a stinger in Week 17 and did not return. His absence continued to fuel a huge game from Aaron Jones, who had 120 rushing yards on 20 carries. Patrick Taylor Jr. also earned increased opportunities as the team's No. 2 running back. It's too early to tell whether Dillon might be able to suit up in Week 18.
Zack Moss Injury Update
Moss (forearm) was officially limited during Tuesday's practice. The 26-year-old missed last Sunday's contest but evidently has a chance to suit up during the Colts' regular-season finale. Even if active this week, Moss remains behind Jonathan Taylor and therefore finds himself off the fantasy radar.
