The NFC Championship Game (also unofficially referred to as the NFC Title Game) is one of the two semi-final playoff games of the National Football League (NFL), the largest professional American football league in the United States.
 The game is played on the penultimate Sunday in January and determines the champion of the National Football Conference (NFC).
 The winner then advances to face the winner of the American Football Conference (AFC) Championship Game in the Super Bowl.
The 1971 San Francisco 49ers season was the team's 22nd year with the National Football League.

 After winning two of their first three games on the road the 49ers lost their first game at Candlestick Park to the Los Angeles Rams 20-13.
 The 49ers would rebound and win the NFC West for the second year in a row by posting a 9-5 record.
 However, for the second year in a row the 49ers season ended in disappointment with a 14-3 loss in the NFC Championship Game to the Cowboys in Dallas.

 Earl Campbell would lead the NFL in rushing for the second consecutive year and set a franchise record for most touchdowns in a season with 19.
 The Oilers would make the playoffs again as a wild card.
 In the wild card game, they beat the Denver Broncos 13-7, and then defeated the San Diego Chargers 17-14 in San Diego to reach their second straight AFC Championship game.
 Unfortunately for them, they had to once again run into the Pittsburgh Steelers, who a year earlier had eliminated them 34-5 in the previous AFC Championship game.
 The Oilers lost the game 27-13.
 The game included a controversial moment in which wide receiver Mike Renfro had a touchdown called back after the referees of the game took a long decision to decide the ruling on the field.
 The call went down as one of the most controversial calls in NFL history.
