New Orleans' cornerback Mike McKenzie suffered a fractured right kneecap on Sunday against the Falcons. McKenzie was carted off the field after defending a third-down pass to Michael Jenkins. He will miss the rest of the season because of a rehabilitation period that could take anywhere from three to six months. "It's real disappointing," said Saints' Coach Sean Payton. "His [last] rehab process was very long and tedious. I'm disappointed for him, and I'm sure the rest of his teammates feel the same way. ... Certainly, it's a blow to our defense. We've just got to get him healthy and get him fixed."
