"They have no common sense or a fan's sensibility," said Maradona, who at the end of the broadcast pulled on a white T-shirt with the message: "Luisito, we are with you."
This is the third time Suarez has been banned for biting an opponent, following similar incidents with Ajax in the Dutch league and Liverpool. He was given a 10-match ban by the Premier League for biting Chelsea defender Branislav Ivanovic in April 2013.
Besides the biting incidents, Suarez has been vilified for racially abusing an opposing player and for a handball on the goal-line during an earlier World Cup quarterfinal. He also has been accused of having a penchant for diving.
But Suarez also stuns fans with moments of brilliance on the field, leaving some to compare him to the likes of Cristiano Ronaldo and Lionel Messi. The Uruguayan striker for Liverpool was last season's player of the year in England's Premier League.
Valdez, the head of Uruguay's soccer federation, said that it was Suarez who was targeted for aggression by the Italians.
"When he falls, several substitutes insult him on the ground and some members of Italy's staff even came off the bench to try to hit him," Valdez said, suggesting FIFA should investigate Italy.
Any appeal by Uruguay must first go to the FIFA appeal committee, said FIFA spokeswoman Delia Fischer. If rejected, Suarez and Uruguay could take the case to the Court of Arbitration for Sport in Lausanne, Switzerland.
"We should withdraw from the World Cup, because what they have done is so lamentable. But at least we can go forward with dignity," said former soccer player Robert Lima, who won several Uruguayan championship with the club Penarol.
