The Chargers are 0-4 as they get ready for a Week 5 date with the Denver Broncos..

Here are five takeaways from Chargers Head Coach Jim Harbaugh’s Monday press conference:

1. Injury updates on Rashawn Slater & Joe Alt

The Chargers lost both of their tackles in Week 4 as Rashawn Slater (ankle) and Joe Alt (neck) each left the game and did not return.

Harbaugh said on Monday that the team is “still evaluating” the severity of Slater & Alt’s injuries, but Slater is “more of a possibility for IR” than Alt.

If either player is placed on Injured Reserve, they would have to miss at least the next four games.

“Next man up. Putting the plan together and treating it like it’s a one-game season. That’s what we’re doing,” Harbaugh said.

Slater was injured with roughly eight minutes left in the fourth quarter of Week 4.

With the Bolts offense at Seattle’s 5-yard line, the Chargers gained three yards on a run to the left but a Seahawks defender rolled up on the back of Slater’s leg.

Harbaugh on Monday confirmed that Slater has a high ankle sprain.

Rookie Logan Taylor, who was already in the game at left guard for Trevor Penning, took Slater’s spot at left tackle.

Rookie undrafted free agent Jacob Spomer then entered the game at center as rookie Jake Slaughter shifted over to left guard.

The injury is a tough break for Slater, who missed the entire 2025 season after suffering a ruptured patellar tendon in training camp last August.

“It’s significant. Great player, we’ll evaluate,” Harbaugh said. “Don’t have an idea for how long.”

Alt also endured a tough 2025 season as he was limited to just six games due to an ankle injury.

He was injured late in the second quarter when a Seahawks defender collided with the Pro Bowl tackle in the pocket.

Travis Burke filled in for Alt the rest of the way at right tackle and played 49 snaps in all in Week 4.

Harbaugh also said Penning remains in concussion protocol.

The Chargers ended Sunday’s game with an offensive line that consisted of, from left to right, Taylor, Slaughter, Spomer, Cole Strange and Burke.

As for Sunday’s home game against the Broncos, Harbaugh indicated that group could be relied upon again.

“I don’t know if it will be the exact way the game ended, but that’s the group that we’ll be talking about working with,” Harbaugh said.

He later added: “We’ll work on that during the week. At one point we had four of the rookie linemen in there and they acquitted themselves well.”
