The New York Giants will be without cornerback William Peterson for the next 4-6 weeks after Peterson suffered a lower back injury. "We're gathering information. There's a lot of options that are available at this time," coach Tom Coughlin said. "There's the possibility of this being something that has to be considered over a 4-to-6-week period. We're just going to have to sit down with all the facts and make that decision."
