Chris Carson, Shaquill Griffin and Ethan Pocic were back at practice as the Seahawks prepare to travel to Philadelphia for “Monday Night Football.”

Pete Carroll said RT Brandon Shell (ankle) is “still hobbling” and will be a “close call” for Monday’s game.

Carroll said rookie Colby Parkinson will jump right into the tight end rotation to replace Greg Olsen, who suffered a torn plantar fascia last Thursday against Arizona.

Carroll confirmed Olsen’s timeline is 4-6 weeks; that could have the tight end back for the playoffs. He plans to make it, tweeting the other day: “I refuse to allow this to be my final moment. I will find a way to finish on my feet!”

While Carson is back, both Bo Scarbrough (hamstring) and Travis Homer (wrist) are out. Scarbrough gained 31 yards on six carries in his first game back with Seattle, but he will need season-ending surgery. Carroll said Homer is “really sore” and has “a little something going on in his wrist” that will take some time to get right.

Carroll said Rashaad Penny, almost a year removed from suffering a torn ACL, has “a really good chance” to return to practice next week. That would set up a three-week activation window, which could have him replacing Homer in time for the final four games or so. A healthy trio of Carson, Carlos Hyde and Penny — two 1,000-yard rushers and a first-round pick — would be fun.

Hyde returned against Arizona and helped lead the way to victory. With Carson back, the Seahawks are whole at running back again — and should continue to lean on them for a balanced attack.

Pocic’s return after missing two games with a concussion should be very helpful as well. Rookie Damien Lewis had to step in for injured Kyle Fuller against Arizona, and the neophyte center predictably had a tough game.

Shell’s possible absence likely means Cedric Ogbuehi would start. He filled in after Shell was injured vs. Arizona. He had a couple tough pass-pro snaps but looked good in the running game.

In other injury news, Carroll is still hoping rookie pass rusher Darrell Taylor will practice soon, but the team is waiting on another medical report before making that progression. Taylor has been rehabbing a college leg injury all season.

Carroll doesn’t know whether DT Bryan Mone will be back this year. He is still in a walking boot and “hobbling around” with a high ankle sprain. Damon Harrison has stepped into his spot, having been promoted this week after exhausting his two practice-squad call-ups.

Stephen Sullivan underwent surgery for a hip flexor. Carroll said, “We’ll get him fixed up and he’ll have a great offseason for us.”

The Seahawks, who have a couple of PS openings, seem poised to bring back 2019 fourth-round WR Gary Jennings.

As Baltimore and other teams continue to deal with coronavirus outbreaks, the Seahawks (knock on wood) have been among the few teams — maybe the only team — to not have any issues.

Carroll said players are now 10 feet apart in meetings and the lockers are farther apart as well. The team also will have one less hour in the VMAC starting Wednesday.

“You need structure, guidelines, goals” Carroll said. “It all comes back to the discipline.”

He said they are using virtual meetings for players/coaches and stressing players should not gather with their extended families for Thanksgiving. That will be the biggest test yet.
