1997 NFL season

Red Cashion and Howard Roe retired. Bill Carollo and Phil Luckett were promoted to referee.

• When a team fakes a punt and throws the ball downfield, pass interference will not be called on the two outside defenders who are actually trying to block a coverage man from getting downfield and might not even know the ball has been thrown.
• In order to reduce taunting and excessive celebrations, no player may remove his helmet while on the playing field except during timeouts, between quarters, and in the case of an injury. Violating the rule results in a 15-yard penalty. This is known as the "Emmitt Smith rule" after the Dallas Cowboys' running back's habit of taking his helmet off every time he scored a touchdown.

• The Atlanta Falcons added new striping on pants, and switched from black to red numbers on the white jerseys.
• The Baltimore Ravens switched to a new numbers style with shadows in the back. White pants were worn with their purple jerseys instead of black pants.
• The Cincinnati Bengals started to use a brighter shade of orange on their uniforms. A secondary logo featuring a leaping tiger was added to the jersey sleeves, and another secondary logo with Bengal's head was also introduced.
• The Denver Broncos introduced new uniforms, changing their primary color from orange to navy blue, and their royal blue helmets to navy blue. The design featured a streak running down the sides of both the jerseys and the pants: orange on the blue jerseys and blue on the white jerseys. The "D" logo with the horse coming out of it was retired in favor of a horse head with blue outlines and an orange mane.
• The Green Bay Packers reduced the number of sleeve stripes from five to three.
• The Jacksonville Jaguars switched from block numbers to a new style font, and added black side panels to the jerseys.
• The Miami Dolphins introduced new uniforms featuring a darker shade of aqua and new shadows in the numbers. The dolphin in the helmet logo was also darkened and resigned to give it a more serious expression.
• The New York Jets discontinued wearing green pants with their white jerseys, and wore white pants for all games regardless of their jersey.
• The Pittsburgh Steelers switched from block to Futura Bold Condensed numbers and names on back on the jerseys, matching the number font on the back of their helmets. A Steelers logo patch was also added to the left side of all jerseys, as an alternative to "fixing" the traditional "missing" logo on the helmet's right side. To celebrate the team's 75th anniversary season, the Steelers introduced 1960s-era throwback uniforms with black jerseys, gold numbers and helmets, and white pants. The nameplate on the white jerseys was made solid black.
• The Philadelphia Eagles added the eagles head logo to the white jersey sleeves (they only did it to the green jerseys in 1996)
• The San Diego Chargers wore white pants instead of navy blue with their white jerseys.
• The San Francisco 49ers removed the gold trim on nameplates to just plain black.
• The Tampa Bay Buccaneers introduced new uniforms, changing their primary color from orange to red, and their white helmets and pants to pewter. Black and orange became trim colors. They also replaced the "Bucco Bruce" helmet logo with a red wind-swept flag featuring a white pirate skull and crossed sabres similar to a Jolly Roger.
• The relocated Tennessee Oilers began wearing an alternative logo on the left side of all jerseys that combined their oil rig derrick logo with elements from the flag of Tennessee.

This was the fourth and final year under the league's four-year broadcast contracts with ABC, Fox, NBC, TNT, and ESPN. ABC, Fox, and NBC continued to televise Monday Night Football, the NFC package, the AFC package, respectively. Sunday night games aired on TNT during the first half of the season, and ESPN during the second half of the season. This was the last season to date that TNT broadcast NFL games, as well as the last for NBC until 2006. When the new TV contracts were signed near the end of the season, Fox retained the NFC package, CBS took over the AFC package, and ESPN won the right to televise all of the Sunday night games.

With Mike Ditka becoming the new head coach of the New Orleans Saints, Sam Wyche was named to replace him on The NFL on NBC pregame show. NBC fired Marv Albert following Week 3 due to sexual assault charges against him; Tom Hammond replaced Albert as the network's #2 play-by-play announcer.

For TNT's final season, Mark May joined Verne Lundquist and Pat Haden in a three-man booth.
