Detroit Lions Could Face Major Secondary Problem Against Vikings

The Detroit Lions are preparing for one of their toughest tests of the season, but a late-week injury could create a serious problem for their secondary against the undefeated Minnesota Vikings. Detroit has already ruled out All-Pro safety Kerby Joseph , and now starting cornerback Roger McCreary is questionable with a foot injury. Joseph's absence was expected after he returned to practice earlier this week but remained limited as the Lions carefully manage his recovery from a knee injury.
