Adding to the difficulty for the Packers: There is pessimism that RB Aaron Jones (calf) will be back for Thursday, I’m told. GB is cautious.

With Williams now out and on the COVID list, according to reports by Tom Pelissero, the current plan seems to be going with Ervin and Williams vs. the 49ers, Rapoport said. Ervin has 10 career carries and Williams has 5. Ervin mostly returned kicks for the Packers while Williams has been on the practice squad. Neither are really great plays against the 49ers, but there could at least be some volume between the two for those owners in need.

Packers running back Aaron Jones didn’t practice at all last week before being ruled out for Sunday’s game against the Vikings, but the team said he would have been able to do something on Monday if the team had a practice.

The Packers will face the 49ers on Thursday night and issued an estimated practice report for the day. Jones was listed as limited by the calf injury that kept him out the last two games. If Jones can't go, it's anyone's guess as to who might take over at running back since Williams was recently listed as a close contact to A.J. Dillon who tested positive for COVID.

Packers LB Kamal Martin and RB Jamaal Williams are considered close contacts for RB A.J. Dillon, who tested positive for COVID-19, source said.

Both did not practice today and the league is determining if they are high-risk close contacts. With Jones dealing with a calf injury it's possible the Packers are suddenly without their top-three backs against the 49ers on Thursday night. Ervin and Williams are next up but it's turning into a situation that will need to be monitored over the next few days to see what Williams' status will be for Thursday.

Packers RB A.J. Dillon is the player who tested positive for COVID-19, per source.

Pelissero went on to say contact tracing is underway. Depending on close contacts, especially within the small RB room, potential competitive implications exist. The Packers are scheduled to play on Thursday night at the 49ers, so this is a situation to watch.

Packer RB Aaron Jones has been ruled out for Sunday's game against the Minnesota Vikings, according to Tom Silverstein of the Milwaukee Journal Sentinel.

Williams filled in admirably in Week 7, but the offense is at its best with a healthy Aaron Jones. The Packers face a weak Vikings defense Sunday.

The presence of Aaron Jones and Jamaal Williams gives Green Bay an extraordinary amount of talent at the running back position, at least for the time being. Jones and Williams are in the last years of their respective contracts.

Williams showed he can carry the workload, as he filled in for an injured Jones this past week. NFL teams in need of a running back next season almost certainly will be watching the tapes to see if Williams might fit their profile. For those in keeper leagues, having Williams on your roster at the end of the year seems like a good idea right now, just to see how things play out next season.
