Los Angeles Chargers wide receiver Quentin Johnston (chest) was listed as a limited participant in practice on Wednesday, according to the team's official injury report. The 0-4 Chargers continue to be the bearers of bad news, listing a whopping 18 players on their injury report, including three receivers: Johnston, Ladd McConkey (foot, did not practice), and Brenen Thompson (quadricep, limited). Johnston has been incredibly disappointing in his fourth NFL season, catching just seven passes for 108 yards and zero touchdowns through four games. After posting a career-best WR34 finish in PPR leagues last year, he has plummeted to WR88 in scoring so far this season. The only good news is that he has maintained a snap share of at least 75% every week. If McConkey is inactive against the Denver Broncos in Week 5, Johnston's fantasy appeal will increase slightly, but he's pretty tough to trust in most leagues right now. Plus, he'd need to clear injury hurdles of his own as he works to overcome this chest ailment.

Los Angeles Chargers offensive tackle Joe Alt (neck) is expected to miss Sunday's Week 5 contest against the Denver Broncos, according to NFL.com's Ian Rapoport. Alt initially suffered the injury in last weekend's loss to the Seattle Seahawks, and although he won't be placed on injured reserve, the star lineman will miss at least a little time. This is brutal news for the Chargers, who have endured an ugly 0-4 start and cannot afford to lose their Pro Bowl right tackle for any amount of time. Quarterback Justin Herbert took a season-high four sacks last week, and he could endure even worse protection this week with Alt sidelined. His absence will presumably bump fourth-round rookie Travis Burke, a Memphis product, into the starting right tackle role against Denver.

Seattle Seahawks running back Zach Charbonnet (knee) was a limited participant in practice on Wednesday as the team begins preparing for Week 5 against the San Francisco 49ers, according to John Boyle of the team's official website. Charbonnet tore his ACL in the playoffs last year, and he didn't quite recover in time for the season opener, so the Seahawks placed him on the PUP list to start the year. Now that he has missed the minimum four games, he's eligible to be activated. The Seahawks definitely don't have to activate him this week if they don't think he's ready, but it's worth noting that Seattle is actively looking to improve its backfield. After placing rookie Jadarian Price (chest) on injured reserve last week, the Seahawks tried to sign Joe Mixon to their practice squad, but the deal didn't progress beyond a physical. Getting Charbonnet back from injury would help answer the running back questions for Seattle, which gave a total of 32 touches to Emanuel Wilson and George Holani last week. Upon his return, Charbonnet would occupy the lead-back role, ranking as an RB2 in fantasy football.

Las Vegas Raiders wide receiver Jalen Nailor (concussion) did not practice on Wednesday as the team begins to prepare for Week 5 against the New England Patriots, according to Anthony Galaviz of The Fresno Bee. Nailor initially suffered the injury in Sunday's loss to the Chiefs, and it forced him to miss part of the game. Now, he's at risk of missing all of next week's game against the Patriots if he doesn't clear concussion protocol in time. It's not often that players are able to clear the protocol in seven days, but it's not impossible. Fantasy managers should monitor the Raiders' practice reports going forward, especially when they release their game status designations on Friday. If Nailor can't suit up this week, Tre Tucker and Cody White would step into larger roles in the passing game.
