Orioles prospect Coby Mayo broke a rib at Triple-A Norfolk. Now it's time to wait.

There is simply no rehabbing a broken rib. Mayo, a Norfolk Tides infielder and one of the Baltimore Orioles' most highly regarded prospects, fractured a rib Thursday when he tumbled down Harbor Park's third base dugout steps and landed on a railing while chasing a foul ball. Mayo, 22, was placed on Norfolk's injured list a day later, with an announcement from the Orioles that “he will miss several weeks.” Mayo was batting .291 with 13 home runs and 37 RBIs through 42 games, sitting out Friday for the first time this season.
