Footbal fans are mourning the loss of Don Shula.
The Miami Dolphins announced the news on twitter saying the 90-year-old passed away peacefully at his home Monday morning.
Shula won the most games of any NFL coach and led the Miami Dolphins to the only perfect season in league history and surpassed George Halas' league-record 324 victories in 1993.
He retired following the 1995 season with 347 wins, 173 losses and six ties, and was inducted into the Pro Football Hall of Fame in 1997.
Shula became the only coach to guide an NFL team through a perfect season when the 1972 Dolphins went 17-0. They won the Super Bowl again the following season, finishing 15-2.
