Ronaldo has confirmed his retirement from football.
The Brazilian legend helped his country to victory in two World Cups, and was named FIFA World Player of the Year in 1996, 1997 and 2002.
Ronaldo, 34, had been expected to quit at the end of the season, but an early elimination of his club, Corinthians, from the Copa Libertadores has brought forward the date.
Ronaldo has struggled in recent years with persistent injury. He damaged his knee in 1999 and then again during a comeback in February 2000, which kept him out of the game for another two years.
His career took him to some of Europe's top clubs, including Barcelona and Real Madrid, as well as AC Milan and Inter Milan.
Another knee injury cut short his playing career at San Siro in May 2008 and he returned to Brazil in 2009 to sign for Corinthians.
But the BBC reports his biggest impact was on the world stage where he scored a record total of 15 goals at three World Cups.
He ended his international career having scored 62 goals in 97 appearances.
