"I think it has been unfortunate mishaps these last few years, but it's definitely something I can't ignore," said Bush, who has missed 10 of the Saints' past 20 games, dating back to December 2007. "I need to focus on strengthening my knee to the point where it doesn't happen again. I'll work with the doctors, trainers and weight staff, doing everything possible to get ready for this season.

"This is my job, this is what I love to do, so it's frustrating. It's nobody's fault, but I won't allow it to happen a third time. Two times is enough. I'll do everything possible to make sure I'm 110 percent. I'll push my butt more this year than I ever have, because of the injuries, and because I owe it to the city, I owe it to the team. I don't feel like I've lived up to the expectations that I have in my own mind."
