Pelissero reports that Metcalf’s injury happened a few days ago.
Carroll said doctors have a clear look on the MRI and think it will be a really quick recovery. However, he offered no details regarding the type of surgery Metcalf will have.
Carroll added that they’re “very optimistic” that Metcalf will be available for Week 1.
