San Francisco 49ers training camp sees rookie De’Zhaun Stribling praised as injuries spark health debate
Four San Francisco 49ers players were injured on the opening day of the 2026 training camp: wide receiver Christian Kirk suffered a calf strain, offensive tackle Vederian Lowe a high‑ankle sprain, defensive tackle Gracen Halton a knee bone bruise, and defensive lineman Andrew Farmer a back injury. Team tight end George Kittle has suggested that the injuries may be linked to low‑frequency electromagnetic fields emitted by a substation located near the team’s practice facility, a theory referenced by researcher Peter Anthony Cowan.
Rookie wide receiver De’Zhaun Stribling has drawn praise from quarterback Brock Purdy, who said the newcomer “understands the route depths and the details and the alignments” and has quickly earned his trust. Former NFL star Dez Bryant, the 2014 league leader in receiving touchdowns, offered a critique of Stribling’s footwork, noting that the rookie’s outside foot position can cause him to “roll into the route” rather than plant firmly.
The discussion highlights both the health concerns surrounding the team's practice environment and the early evaluation of a high‑draft pick expected to contribute to the 49ers’ offense.
