2003 NFL season

The 2003 NFL season was the 84th regular season of the National Football League (NFL).

Regular-season play was held from September 4, 2003, to December 28, 2003. Due to damage caused by the Cedar Fire, Qualcomm Stadium was used as an emergency shelter, and thus the Miami Dolphins–San Diego Chargers regular-season match on October 27 was instead played at Sun Devil Stadium, the home field of the Arizona Cardinals. This was the first season in NFL history where every team won at least 4 games.

The playoffs began on January 3, 2004. The NFL title was won by the New England Patriots when they defeated the Carolina Panthers, in Super Bowl XXXVIII at Reliant Stadium in Houston, Texas, on February 1.

This was the last season until the 2016 NFL season where neither of the previous Super Bowl participants made the playoffs.

Draft
The 2003 NFL Draft was held from April 26 to 27, 2003, at New York City's Theater at Madison Square Garden. With the first pick, the Cincinnati Bengals selected quarterback Carson Palmer from the University of Southern California.

Referee changes
Dick Hantak and Bob McElwee retired in the 2003 off-season. Hantak joined the league as a back judge (the position title was changed to field judge in 1998) in 1978, and was assigned Super Bowl XVII in that position. He was promoted to referee in 1986, working Super Bowl XXVII. McElwee joined the NFL in 1976 as a line judge, and became a referee in 1980. He was the referee for three Super Bowls: XXII, XXVIII, and XXXIV. Walt Anderson and Pete Morelli were promoted to referee to replace Hantak and McElwee.

Major rule changes

 * If an onside kick inside the final five minutes of the game does not go 10 yards, goes out of bounds, or is touched illegally, the receiving team will have the option of accepting the penalty and getting the ball immediately. Previously, the kicking team was penalized, but had another chance to kick again from five yards back.
 * League officials encouraged networks to immediately cut to a commercial break if an instant replay challenge review was initiated. Previously networks were generally not permitted to utilize those game stoppages for their prescribed commercial periods.

2003 deaths

 * John Butler: A former General Manager with the Buffalo Bills, whose team qualified for Super Bowl XXVIII and the San Diego Chargers, he died of lymphoma on April 11, 2003.

Woodley was buried at St. Joseph Cemetery in Shreveport, alongside his parents.
