Miami Dolphins starting cornerback Dimitri Patterson suffered a groin injury in the third quarter of the season-opener against Cleveland and his return is questionable. Patterson who starts opposite Brent Grimes and mans the nickel spot pulled down two interceptions in the first half of Miami's road game against Cleveland. With Patterson sidelined Nolan Carroll has his role elevated paired on the field as the boundary with Grimes. And safety Jimmy Wilson became responsible for the nickel cornerback spot returning to a role he held for most of last season.
