Former NFL coach Buddy Ryan was diagnosed with cancer last week according to his son, Cowboys defensive coordinator Rob Ryan. Buddy Ryan has cancer in his glands that has spread to his neck. He's scheduled to have surgery Sept. 16 in Lexington, Ky., a few days after watching the Cowboys open their season at the Jets on Sunday night. "I'm going to be at the game and see my grandkids and I planned on staying longer," said Buddy Ryan. "But I got to take care of some things."
