SANTA CLARA >> Of course Brock Purdy did not make a grand entrance with dollar bills raining from the ceiling and E-40’s “Niner Gang” anthem bumping as walk-up music.

Instead, Purdy shuffled into Levi’s Stadium auditorium with a red 49ers hoodie complemented by black sweatpants and white sneakers from Adidas, his loyal brand since his 2022 arrival as the NFL draft’s “Mr. Irrelevant.”

The face of the 49ers franchise, essentially from December 2022 through at least the next six seasons, also came with neatly parted hair and nary a whisker around his 25-year-old smile.

Purdy, minus any entourage or even 49ers hierarchy, met the media Wednesday to humbly and graciously discuss the richest contract in team history, a five-year extension worth up to $265 million.

“I always had faith. They started with a very respectable first offer, and from there the communication with my agent was great,” Purdy said. “There was no drama involved. All those moments added up to where I had faith it’d get done and these guys had my back.

“Last week we knew we were at the number and just had to get a couple of things figured out in the language of the contract. And it was a go.”

It was on the Olympic Club’s Lake Course when he learned about the much-anticipated, long-promised deal. His agent, Kyle Strongin, texted him the news, prompting Purdy to gladly accept general manager John Lynch’s FaceTime call.

Purdy was playing alongside his wife, Jenna, as well as center Jake Brendel and his wife, Zan. Brendel relayed in a Wednesday text message that both he and his quarterback were playing well “but once we got the good news, our minds were on other things.” They finished the round after turning to a scramble format to speed up their celebration.Now Purdy can afford membership to the Olympic Club and any other trappings befitting the NFL’s seventh-highest paid quarterback. He can also splurge on a bass fishing boat he’s been eyeing.

Pleasantries aside, are the 49ers going to write checks that Purdy’s body can’t cash?

His establishment as a franchise quarterback hasn’t come without injury issues, though he proclaimed himself 100% healthy midway through the 49ers’ offseason program, with organized team activities starting next week.

Purdy has missed only two starts since assuming the 49ers quarterback role on Dec. 4, 2022, when he replaced an injured Jimmy Garoppolo (who replaced an injured Trey Lance months earlier in the home opener).

Not quite two years ago, Purdy was just starting to throw with a surgically repaired elbow. An InternalBrace procedure fast-tracked his return from an ulnar collateral ligament tear in the 2022 season’s NFC Championship Game at Philadelphia. His recovery went so well, he broke the 49ers’ single-season record with 4,280 passing yards and delivered them tantalizingly close to a Super Bowl triumph before falling in overtime to Kansas City.

Purdy added to his medical file last season with a right shoulder injury forcing him to skip the Nov. 24 loss at Green Bay. On Dec. 30 against the Lions in the 49ers’ home finale, he suffered a right elbow “contusion with nerve inflammation,” thus benching him through the season finale at Arizona.
