What happened: The 49ers said Kyle Shanahan sustained non-life-threatening injuries and will participate in team activities on a limited basis when training camp opens. Adam Schefter reported Shanahan suffered a concussion, a broken nose, three broken ribs and a broken hand.

Why it matters: The accident puts San Francisco under temporary shared leadership as roster evaluations move onto the field. Team coordinators will take on expanded responsibilities during Shanahan's recovery.

What to watch: San Francisco's opening camp sessions will show how much work Shanahan can handle under the limited-participation plan.
