Carroll offered an updated report on the standout cornerback's condition Monday.
"Hopefully, by the end of this week, we'll know more," Carroll said, via ESPN.com. "He had a pretty good exam (Monday), I know that. But he has a serious groin pull. It's not just a pulled muscle. He has some tissue damage and stuff. It's a severe groin pull. They are talking four to six weeks at best. That's a long haul."
