Legendary Dallas Cowboys quarterback Troy Aikman paid tribute to the late Green Bay Packers quarterback Bart Starr on Sunday.

Aikman described Starr as “a true gentleman” in his Twitter post on May 26.

Starr passed away at the age of 85 in Birmingham, Alabama on Sunday. He had battled several health issues in the past, per ESPN.

Starr battled a series of health setbacks recently. In September 2014, he suffered two strokes, a heart attack, and several seizures.

His condition improved after undergoing experimental stem cell treatments. He then overcame a life-threatening bronchial infection in August 2015 and broke his hip in December.

Starr and head coach Vince Lombardi helped build the Packers dynasty in the 1960s. He was also the Most Valuable Player of the first two Super Bowls.

Starr won five titles as the Packers' starting quarterback. He never lost another postseason game after the defeat to the Philadelphia Eagles in the 1960 NFL Championship Game.

Starr's signature moment came in the 1967 NFL Championship Game (more popularly known as the “Ice Bowl”). With a wind chill of -48, it was one of the coldest title games in league history.

In that game, the Packers trailed the Cowboys late in the fourth quarter, 17-14. With 16 seconds left in the game, Green Bay moved the ball to Dallas' one-yard line. Starr called “31 Wedge,” a play designed for running back Chuck Mercein.

Instead of handing the ball off to Mercein, Starr ran the football into the end zone himself. He secured a 21-14 win which propelled the Packers to Super Bowl II against the Oakland Raiders.

Starr's family issued an update to ESPN. Part of it says, “His true legacy will always be the respectful manner in which he treated every person he met, his humble demeanor, and his generous spirit.”

Starr's legacy will live on in the hearts of football fans.
