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.
Allen (quadriceps) will not play in Sunday's matchup with Baltimore.
Allen did not participate in in practice on Thursday or Friday after being limited on Wednesday. It remains unclear what the specifics of his injury are and he's without a timetable to return at this point. Look for Brynden Trawick to see some added reps in the meantime.
Jones has been nursing a knee injury since Week 2 and while he was active for Week 3, he failed to record a carry. However, he continues to play a role in the kickoff return game, as he has fielded kick returns in every game this season. A return to the practice field is a reassuring sign that Jones will be ready for Sunday's tilt with the undefeated Ravens, but look for an official announcement to be made as the weekend approaches.
The Raiders' offensive line took a big hit Sunday, when starting right tackle Menelik Watsonruptured his Achilles tendon in the first half. He will miss the entire 2015 season, per the San Francisco Chronicle.
Smith (suspension) has entered a treatment center, ESPN reports.
Smith's reason for seeking treatment is unclear, but it comes just days after a Periscope video titled "Fire up session" surfaced of an unidentified man, suspected to be him, talking about a hand-rolled cigarette shown on screen. In wake of that video, which appeared under an account previously used by Smith, the NFL has launched an investigation into whether he violated protocols required of a suspended player seeking reinstatement from a substance abuse violation. While that investigation continues, Smith's move to now enter a treatment facility hardly seems coincidental, and more details regarding his situation should surface soon.
