Report: Sean Smith has knee bruise

Miami Dolphins cornerback Sean Smith escaped serious injury when he hurt his left knee in the team's victory over Buffalo, a person familiar with the diagnosis told The Associated Press.

An MRI test Monday determined the injury was only a bruise, the person told The Associated Press, speaking on condition of anonymity because the Dolphins are not releasing details about the injury.

Smith, a fourth-year pro and Miami's best cornerback, can become a free agent this offseason. The Dolphins, who are out of the playoff race, conclude the season Sunday at New England.
