Lockley received the fine Wednesday, six days after New England beat Jacksonville 47-12 in the preseason opener for both teams.
Lockley was flagged for unnecessary roughness in the fourth quarter. Officials said the undrafted rookie from Florida Atlantic led with his helmet while hitting Price. The penalty negated an interception.
Since Lockley is not getting paid a regular-season salary, he only will have to pay the fine if he makes Jacksonville's roster or lands with another team. Lockley also could appeal the penalty.
