Addae will be sidelined for an "extended period of time" after suffering a broken clavicle in the Chargers' Week 2 matchup against the Jaguars, ESPN reports.
It's unclear how long "an extended period of time" constitutes, but it's good new in itself that Addae wasn't immediately shelved on injured reserve. His absence will undoubtedly leave a void in the Chargers' secondary, one that will presumably be filled by either rookie Dexter McCoil or second-year safety Adrian Phillips.
Bosa (hamstring) has been ruled out prior to Sunday's contest against the Saints.
Bosa was able to practice all week, albeit on a limited basis, so there was some potential that the Ohio State product could make his first appearance of the season. Alas, the Chargers will opt to rest their prized first-round pick another week, but there is hope that Bosa will be available when the team travels to take on the Raiders next week.
Brown (ankle) finished with five tackles (three solo) in the Chargers preseason loss to the 49ers.
The rookie linebacker, making his preseason debut after a lingering ankle injury cost him the most of training camp, did have spurts of effectiveness, quickly exploding through the line of scrimmage to harass the 49ers ground attack. Likely a depth option with Manti Te'o and Denzel Perryman slotted to play at each inside linebacker spot, Brown could become an intriguing IDP candidate if either player were to go down.
Flowers picked up seven tackles (five solo) and knocked down one pass in the win over the Jaguars Sunday.
Once again, Flowers was near the top of the tackle totals, as once again the Chargers jumped out to an early lead, forcing their opponent to move the ball quickly through the air. Flowers has racked up an impressive amount of tackles (13 solo) through two weeks, but that number figures to level out as the Chargers find themselves in closer contests.
With D.J. Fluker (ankle) also questionable for Monday's game, it's unclear who will get the start at either guard position against the Steelers, further clouting Melvin Gordon's fantasy value this week.
Gates (hamstring) is listed as doubtful for Sunday's game against the Saints.
Given that Gates did not practice at all this week, we expect that he'll be inactive for the contest, which sets the stage for Hunter Henry -- who was on the field for all 59 of the Chargers' snaps on offense this past Sunday -- to remain busy while starting at tight end in Week 4.
Bailey (ankle) reached an injury settlement with the Chargers on Friday, Michael Gehlken of the San Diego Union-Tribune reports.
Bailey signed with the Chargers in early-August, but didn't see a minute of preseason action. The agreement removes him from the team's injured reserve list, leaving him free to sign with another team.
Square has been suspended four games by the NFL, the team's official site reports.
Square's suspension stems from a violation of the league's substance abuse policy. Early reports indicate that Square did not test positive for a specific substance, but the 27-year-old missed a scheduled test. Both Ryan Carrethers and Tenny Palepoi are likely to fill in during his absence.
Though Charles (knee) will be listed as questionable for Sunday night's game against the Steelers, per BJ Kissel of the Chiefs' official site, ESPN's Adam Schefter reports that the running back is nonetheless expected to make his season debut this weekend.
After approaching the Chiefs' first three games listed as doubtful, it appears as though Charles is poised to see his first game action since suffering a torn ACL last October. Assuming he ends up in uniform Sunday night, we'd still expect to see a solid dose of fellow RB Spencer Ware, though with Charcandrick West ruled out this week, snaps will be up for grabs, which Charles and Knile Davis (to a lesser degree) are candidates to absorb.
Gaines (knee) did not participate in practice on Thursday.
Gaines, who played through the knee injury last Sunday, continues to miss practice time, leaving him questionable for Week 4. If he can't make a go of it this week, look for Steven Nelson and Kenneth Acker to see increased reps.
Hali was limited all last week with a knee injury, but ultimately played in Sunday's game against the Jets. It looks as if Hali is now also dealing with a hand injury, and he should be considered questionable as his status is updated in the next couple of days.
West (ankle sprain) won't play Sunday night against the Steelers, BJ Kissel of Chiefs.com reports.
Though West is out this week, the Chiefs' backfield is poised to be bolstered by the anticipated return to action of Jamaal Charles. Assuming Charles and Spencer Ware -- who has been leading the team's rushing attack out of the gate this season -- can hold up, West's role once he regains his health figures to be limited.
