Chris Cook possibly sidelined until Oct. 11

There are several questions yet to be answered about the condition of Minnesota Vikings cornerback Chris Cook, who reportedly had surgery this week to repair a torn meniscus in his right knee. We don't know, for example, if the injury was a full or partial tear. We also haven't heard an official timetable for recovery from the team.

But after catching up with ESPN injury analyst Stephania Bell, I can tell you that four weeks is the generally accepted time period to recover from surgery to repair meniscus tears. Consider that an educated guess based on typical players. Applied to the Vikings' schedule, it means Cook might not be available until the Oct. 11 game at the New York Jets.

Cook suffered the injury Aug. 25. Four weeks from that point is Sept. 25, the day before the Vikings' Week 3 game against the Detroit Lions. That game would seem to be the earliest return for Cook, but I'm sure the Vikings would be tempted to give him more than the minimum recovery time. If that's the case, he would have two more weeks to regain his strength because of the Vikings' Oct. 3 bye.

The timetable is highly relevant because it appeared Cook was in position to start, at least until incumbent Cedric Griffin returned from his own knee injury. At this point, the Vikings are looking at perhaps three games without two of their top three cornerbacks. Some combination of Lito Sheppard and Asher Allen are expected to hold down the position until Cook or Griffin -- or both -- return to the field.
