The jurors returned the award Wednesday against Dr. John Uribe following a 2½-week trial. Uribe, a former Dolphins team doctor, called the decision a travesty and an appeal is likely.
McDuffie's attorneys called the damage award fair compensation for his lost earnings.
McDuffie sued for negligence and malpractice over treatment for the toe injury he originally suffered in 1999. He reached settlements with several other doctors.
McDuffie played 116 games for the Dolphins from 1993 to 2000. He had 415 receptions for 5,074 yards and 29 touchdowns and also returned two punts for TDs.
