ATLANTA — Roddy White will undergo a minor surgical procedure on his right elbow, Atlanta coach Dan Quinn announced Sunday, thought the long-time Falcons receiver should be ready for the Sept. 14 season opener against Philadelphia. The 33-year-old White developed some unexpected swelling in his elbow late last week and didn’t play in Friday night’s preseason loss to the New York Jets. “There’s something loose in his elbow that caused it to swell up,” Quinn said.
