In Week 1, on September 7, the Baltimore Ravens lost to the Cincinnati Bengals, 23-16. The next day, on September 8, 2014, TMZ released additional footage from an elevator camera showing Rice punching Palmer. The Baltimore Ravens terminated Rices contract as a result, and was later indefinitely suspended by the NFL. Although starting out 0-1 for two straight seasons and having received unwanted media attention for the Ray Rice incident, on September 11, 2014, the Ravens rallied back and beat the Pittsburgh Steelers 26-6, to improve to 1-1. In Week 12, the Ravens traveled down for an interconference battle with the New Orleans Saints, which the Ravens won 34-27, reaching a 4-0 sweep of the NFC south. In Week 16, the Ravens traveled to Houston to take on the Texans. In one of Joe Flaccos worst performances, the offense sputtered against the Houston defense and Flacco threw three interceptions, falling to the Texans 25-13. With their playoff chances and season hanging in the balance, the Ravens took on the Browns in Week 17 at home. After three quarters had gone by and down 10-3, Joe Flacco led the Ravens on a comeback scoring 17 unanswered points, winning 20-10. With the win, and the Kansas City Chiefs defeating the San Diego Chargers, the Ravens clinched their sixth playoff berth in seven seasons, and the first since winning Super Bowl XLVII.
