A look at the impact of McKenzie's injury

Posted by ESPN.com's Pat Yasinskas

ATLANTA -- The news that New Orleans cornerback Mike McKenzie suffered a fractured right kneecap has a lot of implications.

First, you have to wonder if this could mean the end of McKenzie's career. He's 32 and this is the kind of injury that often takes more than a year to recover from. McKenzie already showed an amazing work ethic in bouncing back from a torn ACL in the same knee last December. He was back on the practice field during training camp and his comeback had been a success.

But this is a huge setback and going through major rehabilitation two years in a row could be very difficult at McKenzie's age.

In the short term, McKenzie's injury is another blow to a secondary that already has had plenty of problems. Rookie Tracey Porter, who showed early promise, already is out for the season with an injury.

Randall Gay is the starter on the other side and the Saints are going to have to go with veteran Aaron Glenn, Usama Young and Jason David the rest of the way. Glenn's near the end of his career, David's been inactive the last couple weeks because he can't cover anybody and Young might be nothing more than a special teams player.

Maybe the Saints should have made a stronger run at DeAngelo Hall before he signed with the Redskins last week.
