Bush exited the 49ers’ season-opening 20-3 victory over the Minnesota Vikings with a calf strain after being stopped for no gain on a third-and-1 running play. He did not return to action.
Tomsula said he saw Bush in the training room Tuesday morning and does not believe the injury is serious.
“He looked good,” Tomsula said. “He’s not running, yet. But he looks fine. They’re treating and he’s getting everything checked. . . He walked fine and he was on the table.”
