Sage Jamen Rosenfels is an American former professional football player who was a quarterback in the National Football League (NFL). He played college football for the Iowa State Cyclones and was selected by the Washington Redskins in the fourth round of the 2001 NFL draft. He also played in the NFL with the Miami Dolphins from 2002 to 2005, the Houston Texans from 2006 to 2008, the Minnesota Vikings in 2009, and the New York Giants in 2010. He spent portions of the 2011 season with the Vikings and Dolphins, after being released by the Giants during preseason. Through 2010, he had completed 351-of-562 passes for 4,156 yards, 30 touchdowns, and 29 interceptions, and had a career 81.2 quarterback rating.

The 2004 Miami Dolphins season was the team's 39th overall, and 35th as a member of the National Football League. The Dolphins were unable to improve upon their previous season's output of 10–6, instead only going 4–12 after starting the season 0–6. The team was adversely affected by the premature retirement of their star running back, Ricky Williams, and the trade of holdout defensive end Adewale Ogunleye for wide receiver Marty Booker, as well as career ending injuries to fullback Rob Konrad and defensive tackle Tim Bowens. With this season record below .500 the team would have their first losing season since 1988. To make matters worse, two of their games were postponed due to Hurricane Ivan and Hurricane Jeanne.
