Frederick (illness) is "doubtful" to retake the field this season, Jeff Cavanaugh of The Athletic reports.

EDGE Analysis

Frederick is likely to miss the entire 2018 season as he manages his recovery from Guillain-Barre syndrome, an autoimmune disorder with a high amount of variability in terms of a recovery timetable. The Cowboys remain optimistic that the starting center will eventually make a full return to football, but Frederick appears to be looking ahead to 2019.

Frederick (illness) has regained sensation in his hands, David Moore of the Dallas Morning News reports.

EDGE Analysis

Frederick continues to manage his recovery from Guillain-Barre syndrome, and has reportedly regained feeling in his hands for the first time in nearly three months. The starting center does not yet have sensation in his feet, but his progress is encouraging. "I'm doing good," Frederick said. "I'm getting better, slowly but steady." The veteran center anticipates a full return to football in the future, but it's difficult to imagine that Frederick will play this season.

Frederick (illness) is hopeful that he will be able to play again this season, Todd Archer of ESPN.com reports.

EDGE Analysis

Frederick, who was diagnosed with Guillain-Barre syndrome, was placed on injured reserve last week. While he is optimistic about a return, he is not eligible to play again until Week 10's matchup with the Eagles.

The Cowboys placed Frederick on the Reserve/Non-Football Illness list, per the NFL's official transaction log.

EDGE Analysis

Frederick is dealing with Guillain-Barre syndrome, and he won't be able to practice or play while he's on the NFI list. Joe Looney will remain at center in the meantime.

Fredrick (illness) landed on the Cowboys' injured reserve Saturday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Frederick, who is dealing with Guillain-Barre syndrome, will be eligible to return of the IR for the final three weeks of the season if his health allows it. Joe Looney is expected to replace him at center in the starting unit.

Frederick (illness) has been ruled out Sunday against the Giants, David Helman of the Cowboys' official site reports.

EDGE Analysis

Frederick continues to deal with Guillain-Barre Syndrome, an autoimmune disorder with a high amount of variability in terms of a recovery timetable. The Pro Bowl center should not be expected to return to the field without first logging an extended return to practice. In Frederick's stead, Joe Looney will continue to serve as the Cowboy's starting center.

Frederick (illness) will not suit up in Sunday's regular season opener, Jon Machota of the Dallas Morning News reports.

EDGE Analysis

The Cowboys decision to keep Frederick on the active roster means that he will have an opportunity to return to action as soon as he feels right to play, but it certainly feels as if that might be a while off. The Pro Bowl center continues to deal with Guillain-Barre Syndrome, an autoimmune disorder that carries a high amount of variability in terms of recovery time. As long as Frederick remains out, look for Joe Looney to fill in as Dallas' starting center.

The Cowboys plan to keep Frederick (illness) on the 53-man roster, David Helman of the team's official site reports.

EDGE Analysis

Dallas finds itself in a bit of a sticky situation. On the one hand, Frederick is an elite-caliber center and grades out as one of the best lineman in the NFL. On the flip side, Frederick's diagnosis of Guillain-Barre Syndrome presents a high degree of uncertainty regarding his future and keeping him on the 53-man roster could cut into Dallas' depth elsewhere. Given his value to the team, the Cowboys are not yet ready to make any decisions that will affect his future with the team, but it seems like the team will ultimately be faced to come to grips with some sort of resolution.

Frederick (illness) put in an individual workout Tuesday but is still sidelined at practice, Ian Rapoport of NFL Network reports.

EDGE Analysis

Frederick still has no timetable for a return, as there is so much uncertainty surrounding the auto-immune disease. A decision on whether the center will be placed on injured reserve or not is expected to be made next week.

Frederick announced on his personal Twitter account Wednesday he has been diagnosed with the auto-immune disease Guillain-Barre Syndrome.

EDGE Analysis

Frederick expressed optimism for his return to football as the disease was apparently detected at a relatively early stage, but remains without any sort of return timetable. The 27-year-old seems unlikely to be available for the season opener Sept. 9 against the Panthers, which would bring an end to his 80-game starting streak. Frederick should be considered out indefinitely until indicated otherwise.
