Jimmy Garoppolo's pregame routine as the 49ers' starting quarterback includes a sprint toward the corner of the end zone at Levi's Stadium shortly before kickoff.
He would find large sections of 49ers fans to whip into a frenzy, while their enthusiastic responses would get him amped up even further.
When the 49ers open the regular season on Sunday against the Arizona Cardinals, Garoppolo's pregame hype session will be among the many differences with no fans allowed inside the stadium.
"Obviously, not having the fans out there, not having 'The Faithful,' it's going to be weird and we're going to miss those guys," Garoppolo said. "The energy they bring, it's unbelievable.
"It's invaluable for our team and we're just going to have to bring that energy ourselves. It's one of those things, you've just got to control what you can control and make the best of it."
