Left guard Kelechi Osemele bruised and slightly hyperextended his right knee, but he remained in the game. "He's sore, but he looks OK," Harbaugh said. Osemele downplayed the severity of the injury. … Strong safety Matt Elam suffered a contusion on his right shoulder. "He's a tough guy," Harbaugh said. "He should be OK." … Harbaugh praised rookie free safety Terrence Brooks, a third-round pick who played a season-high 44 snaps Sunday for three tackles, a pass deflection and a fumble recovery. "Terrence is really coming on," Harbaugh said. "He's really getting around the ball. He's playing deep, and he's playing short really well, equally well. What we envisioned when we drafted him. You play well, you earn more time, and he's doing that."
