Sean Payton may be doing business as the Broncos head coach in a much different way than Nathaniel Hackett did a year ago, but Monday delivered a dark bout of deja vu.

Payton heads into the meat of the second week of training camp with an identical question to one Hackett faced almost exactly a year ago.

What is Denver going to do at wide receiver without Tim Patrick and KJ Hamler?

For a second straight summer, the Broncos have questions at wide receiver due to a run of injuries — and, in this case, also an illness with Hamler.

For a second straight summer, Patrick’s season could be over before it began. Medical imaging revealed he suffered a torn left Achilles tendon during a 7-on-7 drill Monday, a source confirmed to The Post.

On Wednesday, Patrick hits the one-year anniversary of tearing his right ACL in Denver’s fifth training camp practice. Instead of clearing hurdles and marching back toward helping Denver on the field this fall, though, he could be looking at another surgery and another taxing rehabilitation.

Payton spoke with reporters immediately following practice before the extent of the injury was known, but confirmed the team was evaluating Patrick’s left Achilles.

“I was watching it directly because he was running a route and it was something we corrected earlier,” Payton said. “It was kind of on air, planted and thought it looked like he slipped.”

Patrick yelled in pain and threw his helmet and his gloves to the ground in frustration as teammates gathered around and the Broncos training staff attended to his lower left leg.

Quarterback Russell Wilson and fellow wide receiver Courtland Sutton helped Patrick get to his feet and provided support until a cart arrived and transported Patrick off the field.

Hamler started training camp on the non-football injury list because of a torn pectoral muscle suffered earlier this year while training on his own, but he revealed on Instagram Monday that he’s also been dealing with a heart condition called pericarditis.

The Broncos formally waived Hamler, a 2020 second-round draft pick out of Penn State, with a non-football illness designation, a procedural move that leaves open the possibility of bringing him back in a few weeks when he’s made progress in his rehabilitation. Even if the plan is to bring him back, for now he will be off Denver’s roster.

As for Patrick, 2024 will be the final year of his contract and he has no guaranteed money left on his deal, which raises the question of whether he’ll ever play for Denver again. There’s a long way to go, but releasing him after the 2023 season would save almost $10 million against the 2024 cap and cost a little more than $3 million in dead money.

In the meantime, though, the Broncos and first-year receivers coach Keary Colbert have a juggling project on their hands.

Last year, Patrick’s injury and Hamler’s long rehabilitation from a knee injury opened the door for undrafted free agent Jalen Virgil to make the opening 53-man roster.

What do the Broncos’ options look like this time around? It will be virtually impossible to replace Patrick’s leadership qualities in the locker room. He wanted so badly to help Hamler this offseason, he invited Hamler to live with him.

“It’s a tough break for us as a team when you see something like that,” All-Pro cornerback Pat Surtain II said Monday. “He’s such a great player, a great leader. When you see him go down like that, it sucks.”

As far as replacing the role and production, the Broncos entered training camp with 12 receivers, so internal candidates exist.

Second-year man Brandon Johnson played well down the stretch in 2022 and gives Payton and the Broncos’ staff another solidly built option — though even at 6-foot-2 and 195 pounds he’s not as physically imposing as Patrick.

Johnson has shown the ability in his young career to play on the perimeter or in the slot and should get a long look over the remainder of training camp. He excelled in preseason games last year before a high-ankle sprain in the finale cost him a chance to make the initial roster.

Another young player who slides up a rung is rookie second-round pick Marvin Mims Jr., who has seen his workload steadily increase in recent days as he rehabs from a hamstring issue. He’s already had injuries to both of his hamstrings dating to the offseason program, Payton said recently, but the coach on Monday expressed confidence in Mims’ progress.

He fits the Hamler profile as a smaller player with explosive down-the-field speed.

Denver also has a pair of players who have spent time with Payton in the past in Marquez Callaway and Lil’Jordan Humphrey, both of whom signed last spring during free agency. Virgil and Kendall Hinton played for Denver last year. Hinton finished with 24 catches and 311 yards and played the third-most snaps among Broncos receivers behind Sutton and Jerry Jeudy.

Denver just worked out a trio of receivers last week and signed Michael Bandy, who spent the past two seasons with the Los Angeles Chargers. The club could revisit that group or re-sign Nick Williams, who’s had two short stints with the club this offseason.

The further down the list you go, of course, the less likely you are to find a real difference-maker.

If Denver decides to mine the late-offseason free-agent market, they will be looking through options that include mostly past-prime veterans or players who have not seen the field much. The former group includes Jarvis Landry, Julio Jones, T.Y. Hilton, Kenny Golladay and A.J. Green. All have been wildly productive receivers over their careers, but none had more than Landry’s 25 catches or Jones’ 299 yards in 2022.

At 6-4 and 201 pounds, free agent Jake Kumerow has played in 46 career NFL games (15, with six starts for Buffalo last year) and would be a potential special teams contributor as well.

Barring a trade, though, the best chance the Broncos have of replacing Patrick and Hamler is going to fall to in-house options.

That list starts with Johnson and Mims and could well include the pair of former Saints, but the group faces a tall task in trying to fill Patrick’s shoes.
