The Chargers placed Reagor (undisclosed) on the practice squad injured list Sunday.

EDGE Analysis

Reagor didn't make Los Angeles' 53-man roster out of training camp but was signed to the team's practice squad. However, he's now dealing with an issue that will make him ineligible to be elevated or signed to the active roster for the first four weeks of the campaign.

The Chargers signed Johnson to their practice squad Sunday.

EDGE Analysis

Johnson was with Green Bay throughout training camp before getting waived on cutdown day. The South Dakota State product will now get a chance to develop on the Chargers' practice squad after going unselected in April's NFL Draft.

The Chargers signed Grimm to their practice squad Sunday.

EDGE Analysis

Grimm didn't make Los Angeles' initial 53-man roster after being signed as an undrafted free agent in late April. However, the Kansas product will get a chance to develop on the team's practice squad. His ability to work as both a receiver and kick returner could help his chances of eventually getting a look on the active roster.

The Eagles have signed Marshall to their practice squad, Olivia Reiner of The Philadelphia Inquirer reports.

EDGE Analysis

Marshall didn't make Philadelphia's 53-man roster but was initially signed to the practice squad. The LSU product was then cut Friday, but he's now back on the practice squad after offensive lineman Kenyon Green was signed from the practice squad to the active roster.

Dickerson (knee) is participating in individual drills at practice Sunday, EJ Smith of The Philadelphia Inquirer reports.

EDGE Analysis

Less than three weeks after undergoing surgery to address a meniscus injury in his right knee, Dickerson is back at practice Sunday. While it's not clear if the Pro Bowl guard will participate in the team portion of the session, Smith notes that in addition to doing individual drills, Dickerson also took reps with the field-goal unit during special-teams drills. There appears to be a growing likelihood that he'll be ready to play in Philadelphia's Week 1 game against the Cowboys on Thursday.

McKee (thumb) isn't practicing Sunday, Eliot Shorr-Parks of Sports Radio 94 WIP Philadelphia reports.

EDGE Analysis

McKee is dealing with a fractured thumb and hasn't practiced for about two weeks. With Philadelphia's regular-season opener against Dallas taking place Thursday, it's looking likely that McKee won't be ready to suit up. If that's the case, Sam Howell would be in line to serve as the backup QB behind Jalen Hurts.

Mukuba (hamstring) is suited up for practice Sunday, Eliot Shorr-Parks of Sports Radio 94 WIP Philadelphia reports.

EDGE Analysis

Mukuba missed practice at the end of the week due to a hamstring issue, but the injury doesn't appear to be serious. While Mukuba is present and in uniform Sunday, it's not yet clear if he'll be limited at all during the session. The rookie second-round pick is slated for a rotational role at safety in his first NFL campaign.

Winfrey exited Sunday's practice with a lower back injury, Todd Archer of ESPN.com reports.

EDGE Analysis

Winfrey had to be helped off the practice field early during the practice session Sunday. The 25-year-old was able to make Dallas' 53-man roster following a strong training camp, and he's slated to work in a rotational role along the team's defensive line if he's able to move past the back injury.

The Vikings have optimism that Nailor (hand) will be able to play against Chicago in Week 1 as long as he doesn't have any setbacks, Jeremy Fowler of ESPN.com reports.

EDGE Analysis

Nailor has been dealing with a hand injury since mid-August and played in only one of Minnesota's three preseason contests while missing multiple weeks of practice. Nonetheless, it appears he's more likely than not to suit up Week 1 provided that he doesn't hit any more roadblocks between now and next Sunday. Nailor could take on an increased role early in the campaign with Jordan Addison set to miss the first three weeks while suspended.

Brown (ankle) is participating in practice Sunday, and Chiefs head coach Andy Reid said the wideout "should be fine" for Week 1 despite not playing at all during the exhibition slate, Charles Goldman of AtoZSports.com reports.

EDGE Analysis

Brown continues to be on track to play in Friday's team regular-season opener against the Chargers in Brazil. Of the receiver's lack of participation in preseason games, Reid stated, "He's a veteran guy. If he was younger, I'd be more worried about it, but he's a veteran guy that kind of knows how to go about it. He should be fine. And we've got guys who can kind of rotate in, too." Brown's ability to suit up Week 1 is especially important to Kansas City with Rashee Rice suspended for the first six games of the campaign and Jalen Royals (knee) not expected to play against the Chargers.
