Josh Jacobs Injury Update
Jacobs (quadricep) was estimated as a non-participant during the Raiders' walkthroughs on Monday and Tuesday. At this rate, he's trending toward missing Thursday Night Football versus the Chargers. If he were to be officially ruled out, Zamir White and Ameer Abdullah would handle the bulk of Las Vegas' touches out of the backfield.
UPDATE: Josh Jacobs (quad) will not play against the Los Angeles Chargers on Thursday Night Football. With Jacobs out, Zamir White and Ameer Abdullah are expected to split touches. Both backs are now risky flex or RB3 options.
Jonathan Taylor Injury Update
Taylor (thumb) missed practice on Tuesday and is trending in the wrong direction for Week 15 versus the Pittsburgh Steelers. With that said, head coach Shane Steichen told the media that he's planning for Taylor to return this season. In the meantime, Zack Moss will continue to operate as the Colts' top running back.
Najee Harris Injury Update
Harris (knee) did not practice on Tuesday. Although this may trigger some initial concern among fantasy managers, the good news is that we saw Harris miss a Tuesday practice last week and manage to play just 48 hours later on Thursday Night Football. Given that the Steelers don't play until Saturday this week, he has ample time to recover and practice. Fantasy managers should monitor injury reports out of Pittsburgh over the next few days. If active, Harris would continue to split touches with Jaylen Warren. They're both RB3 options in fantasy football.
Alexander Mattison Injury Update
Mattison (ankle) was estimated as a non-participant on Tuesday. He picked up the injury during Sunday's game against the Raiders. As of now, it appears that there's a very real chance he'll be inactive for Week 15 versus the Cincinnati Bengals. If so, Ty Chandler would assume lead-back duties, ranking as a mid-to-low fantasy RB3.
Samaje Perine Injury Update
The Broncos estimated Perine (knee) as a full participant on Tuesday. Barring a setback, he'll play in Week 15 versus the Lions, ranking as a high-end fantasy RB4.
