ARVADA – It was a big day for the Broncos — and for star cornerback Pat Surtain II.

On Tuesday morning, the Broncos announced their preferred site for the construction of a new stadium is Burnham Yard in Denver. In the afternoon, Surtain showed up with much fanfare at Arvada High School for the unveiling of his foundation, having donated $50,000 for a complete renovation of a science Inspiration Room classroom and laboratory.

When Surtain showed up, he walked through a maze of students, throwing high-five highs and posing for selfies.

“I appreciate all the love and all the hospitality of Arvada High School,’’ said Denver’s shutdown corner.

Surtain also was excited about the Broncos having targeted a move into a new stadium in 2031 with a retractable roof. That would follow the Broncos’ lease with Empower Field at Mile High expiring after the 2030 season.

“It’s pretty cool,’’ Surtain said. “It’s a testament to show our (Walton-Penner) ownership group always (is) pitching new levels, new heights, seeing what we could do to elevate the team and the organization. I think starting that up, bringing that up is huge for the team and the organization.”

Could Surtain, who is entering his fifth NFL season and is the reigning Defensive Player of the Year, end up playing in the new stadium?

“I can’t wait to see what it brings in the future,’’ he said. “I heard I’m going to be in year 11 (then), so obviously there’s some time before then. But I’m for sure looking forward to it.”

Surtain called it “pretty cool” that there is expected to be “a roof on it.” That would enable the Broncos to host a Super Bowl, a Final Four, a college football title game and other big events. The soonest a Super Bowl could held in Denver would appear to be February 2033 since the NFL usually waits until the second season a stadium is open before putting such a game there.

The cornerback was enthralled on Tuesday about the opening of the rooms at Arvada High for a pathophysiology class. That is a branch of study that focuses on disordered physiological processes associated with disease or injury.

On the wall of the classroom, it reads, “Pat Surtain II Inspiration Room,’’ alongside a number of medical charts. In the adjoining lab, there is a picture of Surtain in uniform on the wall and there are injured dummies on hand, some wearing a Surtain No. 2 jersey. There is new equipment in both rooms.

“It’s a surreal moment,’’ Surtain said. “When I look back at this, I think it’s going to be a moment I realize this is bigger than me. But this is for my mission and that’s giving back to the community. … I can’t wait to see to future doctors down the line from this school, so, with this room, we’re going to develop and build something special.”

This is the third Inspiration Room that Surtain’s foundation has opened in Denver, the previous ones being at Manual High School and George Washington High School.

On Tuesday, Surtain cut a ribbon to officially open the rooms. He then posed for a number of photos, including with students from the class.

“The amount of help this grant has done for the health and science program just this year is amazing,’’ said student Lilyan Holcomb. “And coming from the (previous classroom), with our limited equipment and such an enclosed space, just seeing these two huge rooms and so many more amazing opportunities for Arvada’s future has just inspired me.”

There was plenty of fanfare surrounding Surtain’s visit. When he arrived, he was greeted outside by the school band playing and cheerleaders waving pompons.

When Surtain got inside, he walked down a long hallway while hearing big cheers. Some students held up signs reading, “THANK YOU PATRICK SURTAIN II.” Then he was greeted with applause by students in the pathophysiology class.

“It’s pretty special looking at all the kids’ faces and seeing this room everybody was telling me about and how much interested they are to be in this classroom and now knowing that they have all the resources and tools to succeed at the next level,’’ Surtain said.

It was a special day for both Surtain and the Broncos.
