Packers OLB Frank Zombo will miss a "significant" amount of time after fracturing his scapula in warmups prior to the team's second preseason game. The scapula is another term for the shoulder blade. Zombo might be a candidate for injured reserve, depending on the Packers medical staff's timetable. Zombo and Erik Walden have been rotating with the first-team defense at right outside linebacker, so that job now figures to go to Walden. There have been rumors that Brad Jones, a starter in 2009, is on the roster bubble.
