The 2026 San Francisco 49ers opened training camp with an emphasis on a new defensive scheme and the development of several rookie prospects. Early reports highlighted interior lineman Osa Odighizuwa, a thin safety group, and a roster of first‑year players expected to contribute on both sides of the ball.

A week later, the camp’s opening day produced four injuries, prompting discussion of the practice facility’s environment. While the injuries sparked speculation about low‑frequency electromagnetic fields from a nearby substation, the spotlight also fell on rookie wide receiver De’Zhaun Stribling, who earned praise from quarterback Brock Purdy for his route knowledge and attracted critique of his footwork from former star Dez Bryant. The narrative shifted from initial rookie evaluation to immediate health concerns and early performance assessments.
