He tells his fans not to worry, and that he's OK

Pele is one of the best known names in all of sports

He began his soccer career in the late 1950s

Soccer legend Pele has been moved out of intensive care but remains in a Sao Paolo, Brazil, hospital following treatment for an infection, the hospital said Saturday.

Pele, 74, has no fever and is still on antibiotics, the city's Albert Einstein Hospital said. He was admitted there early last week for a urinary tract infection.

Pele posted a message to his Twitter followers Friday telling them not to worry.

"Thank you very much, I know everybody (is) worried about my health, but I'm ok," he wrote. On Facebook, he posted a video of himself strumming a guitar.

Known as "The Black Pearl" and simply "The King," Pele is one of the best known names in all of sports.

He burst onto the scene as a teenager, helping lead his native Brazil to the 1958 World Cup championship. Pele went on to star on two other World Cup title teams as well, in 1962 and 1970, in addition to a breakthrough career with the Brazilian club Santos and later with the New York Cosmos of the now-defunct North American Soccer League.

In 2000, he and Argentina's Diego Maradona were named co-Players of the Century by FIFA, the international soccer governing body.

Santos named him a lifetime ambassador for the club, Pele told fans this week.

"It is exciting to know that I will be wearing the shirt of my favorite team for the rest of my life," he wrote on Twitter. "I expect to keep bringing pride and joy to Santos fans all around the world."

Even after retiring from football, Pele has remained in the public eye as a product pitchman, ambassador for the sport of football and advocate for Brazil's poor, having grown up among them in the inland city of Tres Coracoes.
