Miami Dolphins head coach Don Shula has passed away at the age of 90.

Barry Jackson of the Miami Herald reported the news on Monday morning after one of Shula's children confirmed. A cause of death was not immediately known.

The Dolphins released an official statement addressing Shula's passing.

Shula is the all-time leader in wins (347) and games coached (526). He is best known for leading the Dolphins to their perfect season in 1972 while winning two Super Bowl titles. He coached a record 33 consecutive seasons as head coach.

The legendary Dolphins coach exemplified what it meant to be a winner. He began his head coaching career with the Baltimore Colts in 1963 and posted a 71-23-4 record (.755 winning percentage). After beginning his stint with the Dolphins in 1970 — his tenure didn't end until 1995 — he would not suffer his first losing season until 1976, 14 years into his career. In fact, Shula suffered only two losing seasons during his 33 seasons as a head coach.

Not only did Shula coach, he also played seven seasons as a defensive back. Due to his legendary coaching stature, Shula was inducted into the Pro Football Hall of Fame in 1997.

Our thoughts and condolences go out to Shula's family.
