(Reuters) Teixeira, president of the Brazilian Football Confederation (CBF), sent a signed letter from his doctor saying he could not be subjected to any stress as he had been suffering from heart problems.
For the same reason, Teixiera has taken medical leave from his CBF post and is not expected to return until next year.
"If Ricardo Teixeira is unable to work for six months, it would be best for him to step down because Brazil is at a decisive stage in the World Cup qualifying campaign," Alvaro Dias, president of the commission of inquiry, said.
"For the health of football, it would be best if all the CBF directors resigned."
Teixeira, who has run the CBF for 12 years, has been one of the central figures in the two-pronged investigation that has been carried out by commissions of inquiry in both the Senate and the lower house.
The commissions of inquiry were set up last year following a public outcry into the alarming decline of Brazilian football, which has been hit by administrative chaos, plummeting attendances and a mass exodus of the top players abroad.
Even the famed national team has been affected, slumping to a series of unprecedented defeats at the hands of teams Brazil would in the past have been expected to beat handsomely, such as South Korea, Chile, Paraguay, Honduras, Ecuador and Australia.
Congressmen investigating suspected corruption and mismanagement in Brazilian soccer have called on the game's chief Ricardo Teixeira to resign after he failed appear to answer questions because of ill-health.
