NEW YORK (AP) — The Miami Dolphins will appear on Hard Knocks this summer. HBO announced that the team will be the newest subject of its popular reality series documenting NFL training camps. The seventh season premieres Aug. 7, with four more one-hour episodes airing on subsequent Tuesdays. Hard Knocks was not produced last year because of the NFL lockout. In 2010, the Dolphins’ AFC East rivals, the New York Jets, were the subject of the show, making coach Rex Ryan a reality star.
