Jacobs (illness) was listed as a non-participant in Wednesday's walkthrough, Rachel Gossen of the Raiders' official site reports.
It remains to be seen if Jacobs' illness might impact his availability for Thursday's practice, but all things considered league-wide his status is now worth monitoring as Sunday's game against the Broncos approaches. Next up for the Raiders' RB reps if Jacobs misses the session or is limited are Peyton Barber and Jalen Richard.
