The
Miami Dolphins have already lost one starting cornerback to a season-ending groin injury, which explains why the team appears to be taking a cautious approach with the other.
Brent Grimes, the Dolphins' shutdown cornerback, wasn't allowed to practice with the team on Wednesday because of a groin injury he suffered in Sunday's 24-20 win over the
New England Patriots.
Dimitri Patterson, who began the season as the starter opposite Grimes, was placed on injured reserve last week because of a groin injury he'd battled all season.
