Eagles center Cam Jurgens (concussion) was practicing again on Friday and is officially listed as questionable for Sunday’s game in North Texas.

Jurgens suffered a concussion late in the Eagles’ win over the Lions on Sunday night but has been progressing through the NFL’s concussion protocol this week. After missing practice on Wednesday, Jurgens was a limited participant on Thursday and a full participant on Friday. He has been trending the right way.

The last step for players to get through the NFL’s concussion protocol is to get cleared by an independent neurologist.

Here are all the game statuses for Sunday:

Out: OT Lane Johnson (foot)

Questionable: C Cam Jurgens (concussion), OT Myles Hinton (back), OL Willie Lampkin (knee/ankle)

If Jurgens can’t clear the concussion protocol in time for Sunday’s game, veteran Brett Toth would make his third start in four games. Toth started against the Giants and Packers when Jurgens was out with a knee injury.

The Eagles will be without at least one starting offensive lineman on Sunday in Dallas. Lane Johnson (foot) missed all week of practice after suffering a Lisfranc sprain against the Lions. Johnson is expected to miss 4-6 weeks, but the team is hopefully he’ll return for the playoffs.

In the meantime, veteran Fred Johnson will be the Eagles’ starting right tackle. The Eagles brought back Johnson in August via trade with the Jaguars.

Every other member of the Eagles’ 53-man roster aside from Lane Johnson was practicing on Friday.

Both Hinton (back) and Lampkin (knee/ankle) are rookie offensive linemen who are still on IR but have had their practice windows open. If either of them are going to be available for Sunday, they would need to be activated to the 53-man roster by 4 p.m. on Saturday.
