Chargers Training Camp is officially off and running as the Bolts held their first practice Thursday morning.

The non-padded session lasted less than 90 minutes at The Bolt in El Segundo.

Here is the Chargers Camp Report from Thursday's practice:

1. Herbert airs it out

Justin Herbert wasted no time with a highlight-reel play to open camp.

The Chargers worked on individual and special teams drills for the first few periods in practice before getting into an 11-on-11 drill.

Herbert's sixth play had fans out of their seat as he connected with Jalen Reagor on a 50-yard touchdown pass down the right sideline.

And while Herbert showed off his trademark cannon on the play, Reagor deserves credit, too, for a tumbling catch against Cam Hart that saw the wide receiver stretch the ball over the front right pylon.

"I think he does everything really well," Herbert said of Reagor after practice. "He's one of those guys, whether it's quick game or intermediate or the deep balls like that, he's definitely fast enough to take the top off and he's such a great rute runner that he's able to beat man coverages.

"Another guy you feel comfortable going to whether it's zone or man. He just finds a way to get open," Herbert added.

Herbert also looked sharp in a red-zone, 7-on-7 drill when he found rookie wide receiver KeAndre Lambert-Smith for a 10-yard touchdown in the back of the end zone.

Day 1 is in the books, but Herbert looked in midseason form.

2. A look at the O-line

One of the biggest position battles in camp will be at left guard and center, where Zion Johnson and Bradley Bozeman are expected to eventually settle into those starting spots.

But it remains to be seen which position each will play as the two rotated at those spots during the offseason program.

Chargers Head Coach Jim Harbaugh said Thursday that trend will continue for the foreseeable future. On Thursday, that meant Bozeman at center and Johnson at left guard.

"That's the plan right now. I don't know how many days but that will do like that until we lock it in," Harbaugh said. "We know we have a trusted agent and known friend in Brad Bozeman at center, and we know he could be a really good guard and has been a really good guard.

"Zion, known friend and trusted agent [as a] starting guard," Harbaugh added. "Will it be a better combination with him at center and Boze at guard? Or is it going to be better with Zion at guard and Boze at center. We'll find out."

Herbert said: "It's a little different going from guy to guy every day, but that's the great thing about fall camp. We've got so many reps and we're going to get so many snaps under center and in the [shot]gun. We're going to feel comfortable with whoever it ends up being and we're going to have complete faith in them."

The rest of the Chargers starting offensive line consisted of left tackle Rashawn Slater, right guard Mekhi Becton and right tackle Joe Alt.

Harbaugh, by the way, said competition is open for all starting spots when it comes to the offensive line, but noted the team envisions Trey Pipkins III as their swing tackle with Jamaree Salyer providing strong depth along the interior.

"We've got a great starter in Trey Pipkins, too, but in an ideal world Pip is our swing tackle," Harbaugh said. "We know if anything happens to our two great [tackles] then we've got a great guy who can go in and there'll be little to no drop off.

"And Jamaree Salyer has made tremendous gains. He just looks good, much more lean muscle mass," Harbaugh said. "He's on track so excited what he can accomplish. If he's the best player, he'll be in there, too."

The next group featured, from left to right, Pipkins, Salyer, Andre James, Branson Taylor and Corey Stewart.

Ryan Nelson, Nash Jones, Josh Kaltenberger, Karsen Barnhart and Elijah Ellis made up the final group from left to right.

3. A handful of PBUs

Derwin James, Jr. put it best when describing Day 1 of camp.

"First day, always good to get your feet wet," James said after practice. "It feels good to be back out there."

And with the pads not coming on until next week, think of these first few training camp practices as an extension of June's minicamp.

Even so, a handful of defenders made some solid plays despite not being able to play as physical as they likely want.

Ja'Sir Taylor knocked a pass away in a team drill before Daiyan Henley forced an incompletion and nearly hauled in a bobbled interception.

Eric Rogers also had a pass breakup against Herbert's group before Hart had good coverage on Quentin Johnston to force an incompletion.
