Prepare to be sleep-deprived, Miami Dolphins fans. A year after getting largely overlooked, the Dolphins will get plenty of national exposure in 2013, assigned three prime-time games when the schedule was announced Thursday. The highlight: A home affair with the Bengals on Halloween night (a Thursday night), which will air on NFL Network. The Dolphins also will play on ESPN’s Monday Night Football on Sept. 30 at New Orleans and Nov. 11 at Tampa Bay. It’s a significant boost for the Dolphins, who had just one prime-time game in 2012 — and that was a Thursday night contest at Buffalo. Perhaps spurred by the splash Miami made in free agency — which included the signings of Mike Wallace, Dannell Ellerbe and Brent Grimes — the NFL granted the Dolphins three nighttime games for the first time since 2010. They open the season Sept. 8 at Cleveland, where the Browns will be coached by former University of Miami offensive coordinator Rob Chudzinski. They will close the year at home against the rival Jets (Dec. 29) for the second time in three years. In between, the Dolphins will play at Indianapolis (Sept. 15), host the Falcons (Sept. 22) and the Super Bowl champion Ravens (Oct. 6) before a Week 6 bye. The Dolphins then have back-to-back divisional games (home against Buffalo on Oct. 20 and at New England on Oct. 27) ahead of back-to-back prime-time games.
