Although All-Pro safety Derwin James Jr. will miss his fourth consecutive game because of a hamstring injury, the winless Chargers are coming off their bye week with some much-needed reinforcements.

Wide receivers Ladd McConkey (concussion) and Tre’ Harris (hamstring) and offensive tackle Joe Alt (neck) are all set to play Sunday against the Rams at SoFi Stadium.

“It’s a good thing,” Chargers coach Jim Harbaugh said. “It’s good to have them back out there. Good work put in. Feel good about the preparation and feel like we’re in a good place, ready to go.”

Harris and McConkey have been the Chargers’ top two receivers when available this season. Harris leads the team in receptions (15), receiving yards (225) and targets (26), while McConkey is right behind him with 13 receptions for 200 yards on 18 targets.

And Alt’s return instantly improves the Chargers’ banged-up offensive line, which has allowed Justin Herbert — who carries a league-worst 29.4 quarterback rating — to be sacked nine times in the two games the offensive tackle has missed.

“Regrouping. Retooling. Thought it was a really good week of preparation,” Harbaugh said.

Offensive coordinator Mike McDaniel and his unit desperately need all hands on deck.

The Chargers are averaging a league-worst 15 points per game and are tied for the second-fewest yards per play (4.6).

“I spend all of my time focusing on the best plan for the players that we have available this week, to attack the defense we have,” McDaniel said. “And then you have to illustrate, in a good manner, what the vision is for how we’re going to play and improve the results.”

McConkey, Harris and Alt returning will help McDaniel’s cause, especially as wideout Brenen Thompson (quad/hamstring) remains out alongside key offensive linemen Rashawn Slater (ankle) and Kayode Awosika (fibula).

Meanwhile, the Chargers’ defense, which allows the eighth-fewest passing yards per game (206.2), must hold the fort again without James, who suffered a rehab setback.

“You can’t replace Derwin,” defensive coordinator Chris O’Leary said. “It’s not possible. He’s one of the best in the league, if not the best in the league.”

That task will be even harder if cornerbacks Donte Jackson and Rodney Shelley, who are both questionable with hamstring injuries, can’t play.

“For us, our message from the offseason to now is: team defense,” O’Leary said. “Play together. We’re not going to put too much on one guy’s plate. … And that’s really just spiked, now that Derwin’s out.

“It’s just a group effort, and I think the guys have done a great job.”

O’Leary’s defense has bent but rarely broken all season.

McDaniel’s offense, however, could use a breakout performance. And with more of Herbert’s primary targets fully healthy, there’s no better time than Sunday.

“It was much-needed,” Herbert said of the bye.

The Chargers will have their two top wide receivers back Sunday as they seek their first win of the season against the undefeated Kansas City Chiefs.

Ladd McConkey (foot) and Quentin Johnston (chest) are each off the injury report after missing the Chargers’ Week 5 loss to the Denver Broncos.

“Heck yeah. Fired up about that,” Chargers coach Jim Harbaugh said. “Really good week of preparation. … Excited for this opportunity.”

Harbaugh said he didn’t know whether McConkey or Johnston would have limited snaps.

The Chargers, though, could use all the reinforcements they can get. They enter Arrowhead Stadium averaging 16.8 points per game — third-worst in the NFL — eager to snap a nightmare five-game skid heading into their bye week.

Tre’ Harris, who led the Chargers’ banged-up wideout unit against the Broncos, is out with a hamstring injury; KeAndre Lambert-Smith (hamstring) is questionable with the same ailment.

Rookie wideout Brenen Thompson (quad), whose unparalleled speed helps open up offensive coordinator Mike McDaniel’s scheme, is also questionable after missing the last three games.

Quarterback Justin Herbert isn’t the type to complain about working with limited options.

“You have to try to keep the game the same,” Herbert said. “You can’t let it affect you too much.”

But it’s refreshing to have McConkey and Johnston back.

“Yeah, it was awesome to see those guys out there,” Herbert said Wednesday. “They’ve made so many plays for us. And, you know, we expect them to make more plays for us, too.

“To have those guys back out there — I know they’re doing everything they can to be out back out there for this team.”

Unfortunately for the Chargers, the offensive line is still severely hobbled.

Right tackle Joe Alt (neck) and left guard Kayode Awosika (fibula) remain out, meaning rookie center Jake Slaughter will continue to anchor a front that has featured several inexperienced players over the last two games.

The offensive line was already down left tackle Rashawn Slater (ankle), who is on injured reserve, and center Tyler Biadasz, whose season was over before it started when he sustained an anterior cruciate ligament tear in August.

McDaniel liked what he saw from the offensive line against the Broncos. He’s optimistic, really with no other choice, about the unit entering the matchup with the Chiefs, a team allowing the NFL’s seventh-fewest points per game (19.3).

“There [were] a lot of positives from the offensive line perspective,” McDaniel said. “I’ve never been a part of that many rookies playing at once. Fortunately, we drafted the right guys, and they [are] made of the right stuff. … There was a lot to build on.”

Kansas City, as usual over the last decade, will be a force to reckon with — especially at home.

Quarterback Patrick Mahomes and new running back Kenneth Walker III have the Chiefs averaging the fifth-most points per game (29.5) and the second-most yards per game (412) amid a 4-0 start.

“Explosiveness, man,” Chargers edge rusher Khalil Mack said. “[Walker is] breaking tackles. Just the ability to create plays between him and [Mahomes], man. That’s a special duo there in that backfield.”

One the Chargers will have trouble stopping, as they’ll also be without key defensive players like safety Derwin James Jr.

Winning in the NFL is already challenging enough. But for the injury-riddled Chargers, it’s been impossible so far, and it won’t be any easier Sunday.

“Communicating and keeping your poise and all those factors,” Harbaugh said of preparing for the loud environment in Kansas City.

Chargers offensive coordinator Mike McDaniel didn’t shy away from discussing his job security Thursday amid a frustrating 0-5 start to the season.

“I feel like it’s core to my job to always feel that way,” McDaniel said when asked if he’s coaching for his job. “I need to do the very best I possibly can, all the time, because [of] the players, the organization, the fans.

“So, that’s second nature. … I think it’s disrespectful to all those that choose to invest in our game and our team to not look at things that way. The second you get comfortable in this league, it’s a wrap; it’s too good. I will be doing my very best, because from an integrity standpoint, I think it’s really insulting to do anything else. And that won’t change.”

McDaniel says his determination is unwavering. His place in the Chargers’ organization, however, might not be if things don’t change soon.

The Chargers, who rank 10th in total yards allowed per game on defense (311.6), enter Sunday’s road game against the undefeated Kansas City Chiefs averaging just 16.8 points per game, the third-lowest mark in the NFL above just the also-winless Miami Dolphins (14.0) and Tennessee Titans (11.6). Quarterback Justin Herbert ranks 22nd in passing (937 passing yards) and is last in the NFL in total quarterback rating (26.6).

Injuries have played a significant role in the Chargers’ offensive struggles. Eight offensive players either didn’t practice or were limited in practice because of injuries on Wednesday. Four rookies started on the offensive line in Sunday’s loss to the Denver Broncos and wide receivers Ladd McConkey, Quentin Johnston and Brenen Thompson, didn’t play.

McDaniel insists that he’s been giving the franchise all he has.

“I would be so embarrassed if I told you, ‘Well, now I’m going to try harder,’” McDaniel said. “Like, what? What have you been doing? I’m confident in the players that we have. The improvement that I see before the results generally lead to good things. But talk is cheap. We got to do.”
