LOS ANGELES, Sept 6 (Reuters) - Veteran rocker Bruce Springsteen said on Wednesday he was indefinitely postponing eight tour dates this month with his E Street Band, citing medical treatment he is undergoing for peptic ulcers. Ticketholders for the postponed concerts were told they would receive information regarding rescheduled dates. The other postponed dates were Sept. 9 in Baltimore, Sept. 12 and 14 in Pittsburgh, Sept. 16 in Uncasville, Connecticut, and Sept. 19 in Albany, New York. Peptic ulcers are open sores that develop on the inside stomach lining and the upper portion of the small intestine, with the most common symptom being stomach pain, according to the Mayo Clinic.
