Christian McCaffrey won't play this preseason for the San Francisco 49ers as he recovers from a calf strain. McCaffrey strained the calf on Sunday and had to sit out team drills. When the Niners practiced Tuesday, McCaffrey did not participate, leading coach Kyle Shanahan to confirm the injury. The reigning NFL Offensive Player of the Year is expected to miss at least one week of practice, and the 49ers don't plan to risk him hurting it during one of their three preseason contests. "He did it a couple days ago," Shanahan said. "It's all right. He didn't pull it or anything, but you guys probably won't see him this preseason.
