Minnesota Vikings rookie cornerback Chris Cook has been ruled out of Monday night's matchup with the New York Jets, one day after a report that he tore the meniscus in his left knee.
Vikings coach Brad Childress confirmed Saturday that Cook had a "procedure" done on his knee for an injury suffered during Week 3's 24-10 victory over the Detroit Lions.
Cook missed the Vikings' first two games after tearing the meniscus in his right knee during the third preseason contest, returning to the field for the Sept. 26 victory over the Lions. He was in the starting lineup for his regular-season debut, and he participated in practice Monday when the Vikings returned from their bye week.
Another torn meniscus likely would keep Cook off the field for a few weeks, but Childress said he anticipates the rookie will return faster from this meniscus tear than the one he suffered during the preseason.
Vikings quarterback Brett Favre (ankle, elbow), tight end Visanthe Shiancoe (hamstring) and center John Sullivan (calf) were all limited participants in Saturday's practice, but only Sullivan was questionable.
Childress said Favre's elbow was inflamed. Favre was seen wearing a sleeve on his right arm in practice this week, and he was icing his elbow during a post-practice news conference Thursday.
"It was not an issue before we went on the bye," Childress said. "We worked pretty good on Monday and Tuesday out here. It flares up every now and again. MRI just says he has a little inflammation. You manage it."
Childress said Sullivan was improving enough that he would fly with the team to New York in hopes of his injured calf improving over the next two days.
