The Braves aren't ''overly concerned'' that Brian McCann (side) will miss significant time. McCann left Friday's game with what was described as an intercostal strain on his right side. "We'll know more tomorrow," Braves manager Fredi Gonzalez said. "It's up high. It's in between the ribs so we're not overly concerned. Sometimes if it's really low with the oblique it's a little different story. But we'll know more tomorrow." The injury is unrelated to the oblique strain that derailed McCann's 2011 season. Backup David Ross is expected to start Saturday against the Pirates.
