LOS ANGELES — Losing to older brother John Harbaugh and seeing the Los Angeles Chargers’ four-game winning streak snapped Monday night might be the least of Jim Harbaugh’s problems this week.

The Chargers are holding their breath that running back J.K. Dobbins isn’t seriously hurt after he left with a knee injury late in the first half of the Chargers’ 30-23 loss to the Baltimore Ravens.

Harbaugh, who dislikes discussing injuries and eschews questions about any player’s status with the tried and true “I’m not a doctor” answer, will get plenty of inquiries about Dobbins’ health this week.

There were no updates on Dobbins’ status Tuesday. The Chargers return to practice on a short week before having to travel cross-country to Atlanta.

Dobbins’ Impact on Chargers’ Offense

After injuries derailed Dobbins’ four years with the Ravens, the 2020 second-round pick decided to bet on himself by signing only a one-year deal with the Chargers.

Though the first 10 1/2 games, the bet appeared to be paying off. Dobbins had 40 yards on six carries when he was wrenched backward by linebacker Malik Harrison and then gang-tackled on a play for no gain on third-and-1 at the 50-yard line.

Dobbins is fourth in the AFC in rushing with 766 yards and averages 4.8 yards per carry, third highest among AFC backs with at least 100 carries. He has been considered among the candidates for AP Comeback Player of the Year after suffering a torn Achilles tendon in last season’s opener.

Dobbins’ production throughout the season has made the offense more balanced. Los Angeles had 14 rushes for 68 yards before he was injured. They had seven carries for 15 yards the rest of the game.

Offensive Struggles Without Dobbins

Without Dobbins and a 14-13 deficit at halftime, the Chargers tried to count on Justin Herbert and the passing game to rally back. Herbert was 11 for 22 for 125 yards and sacked three times in the five drives after Dobbins’ departure and didn’t get back into the end zone until Gus Edwards’ 1-yard run with 46 seconds remaining.

Edwards will be counted on to be the lead back if Dobbins has to miss games. Edwards missed four games during the middle of the season because of an ankle injury and has 25 carries for 93 yards in three games since returning to the lineup.

Hassan Haskins and rookie Kimani Vidal will be counted on to provide depth.

“Obviously, I’m hoping J.K. is OK. Gus has been an awesome addition, being able to run and go and get some yards,” Herbert said. “We just got to stay with it. I think that offensive line has done a great job all year. It didn’t go our way today, but we’re going to keep pounding the ball and keep getting after it.”

Dobbins’ injury also could not come at a worse time for the Chargers. They are 7-4 and hold the sixth seed in the AFC, but have tough upcoming tests against playoff contenders Atlanta (6-5), Kansas City (10-1), Tampa Bay (5-6) and Denver (7-5) the next four weeks.

What’s Working

Herbert on the run. Herbert has at four scrambles of at least 12 yards in the past five games and got his second rushing touchdown of the season on the opening drive with a 5-yard carry up the middle.

What Needs Help

Not giving up big-play touchdowns. Rashod Bateman’s 40-yard touchdown late in the second quarter (which would have been pass interference on Kristian Fulton if it wasn’t completed) marked the third straight game the Chargers allowed a passing TD of at least 40 yards. They had allowed only two in the first nine games.

Stock Up

LB Joey Bosa had four tackles, his most since he had seven in Week 1 against the Raiders. Bosa missed three games earlier in the season because of a hip injury, but had only two tackles in the four games since his return until Monday night.

Stock Down

WR Quentin Johnston is the second Chargers receiver since 2009 to be targeted at least five times and not have a catch according to Sportradar. Travis Benjamin also had five targets and no receptions against the Jets in 2017. Besides being held without a catch, Johnston had two critical drops during the second half.

Injuries

In addition to Dobbins, CB Eli Apple suffered a hamstring injury in the first half and did not return. CB Cam Hart was inactive because of an ankle injury and was in a walking boot. LB Denzel Perryman (groin) and TE Hayden Hurst (hip) were also inactive because of injuries.

Key Numbers

57 — Points allowed by the Chargers in the past two games. They had given up 68 in their first five games after their bye week.

73 — Games it took for Herbert to reach 1,800 completions, tying him with Kansas City’s Patrick Mahomes as the fastest players in NFL history to reach that mark.

6 — Games where Daiyan Henley has had double-digit tackles. The second-year linebacker had 10 tackles (four solo) on Monday night.

What’s Next

The Chargers will make their second trip in three years to Atlanta on Sunday. They won the 2022 meeting in Week 9 when Cameron Dicker hit a 37-yard field goal on the last play of the game. Los Angeles is 2-0 against the NFC South this season and has a four-game winning streak against teams in the division.
