On Saturday, the Buffalo Bills held the first public event at the new $2.2 billion Highmark Stadium during the annual "Return of the Blue & Red" training‑camp practice. The venue welcomed 51,807 fans—a team record for a practice—and gave players a first look at the state‑of‑the‑art field. Quarterback Josh Allen made a splash by stepping onto the turf in the new alternate "Nickel City" uniform, a look that sparked controversy but earned his vocal support. He also played catch with fans around the track, pausing to let a sign reading "the house that Allen Built" line the stands behind him. The rest of the offense wore the team's home blue jerseys while the defense stayed in away whites, and backup QBs Kyle Allen and Shane Buechele joined the show.

Players praised the natural grass, with right tackle Spencer Brown calling it "perfect" and tight end Dawson Knox declaring it the "biggest difference" from artificial turf. The field, Kentucky Bluegrass cultivated by Tuckahoe Turf Farms, will rely on underground heating to prevent freezing in winter. Fans also lined up for the stainless‑steel bison family statues in the arena, a new addition that will be lit up in blue and red for future games.
