49ers change up their left guard rotation; Mike Evans and Jacob Cowing return

The San Francisco 49ers altered their left guard rotation, reporting on June 3, 2026, that tight end Khalil Dinkins underwent a tryout. This move followed the participation of tight ends Brayden Willis, Josiah Deguara, and Hayden Rucci in 33 to 37 snaps during the preseason opener. The starting left guard, Connor Colby, and backup Carver Willis shared the majority of playing time during move-the-ball drills.

Robert Jones, who guarded right guard on the second team, will likely take the stage in the first preseason game, with Willis and Colby set to follow. Head coach Kyle Shanahan indicated that Jones meets the requirements to compete for the starting position, but Willis and Colby could be the primary options. Jones' participation in his first live game since 2024 was acknowledged, and Coach Shanahan expects him to manage any post-game discomfort.

Defensive coordinator Raheem Morris expressed satisfaction with Halton's performance, particularly his execution of a sack that was ultimately negated. The team also revealed that rookie Boomer Williams stood out in practice, impressing Coach Shanahan with his explosive speed and powerful play.
