FIFA has taken note of the official confirmation received in writing last night from the CBF and the LOC of Ricardo Terra Teixeira’s resignation from his functions as chairman of the 2014 FIFA World Cup Brazil™ Organising Committee (LOC) and president of the Brazilian Football Association (CBF). 
The CBF and the LOC have also officially confirmed to FIFA that Jose Maria Marin will be the successor of Ricardo Teixeira in those two positions. 
At the time of writing, Ricardo Terra Teixeira remains a FIFA Executive Committee member. FIFA has not received any official communication from Teixeira or from CONMEBOL regarding this position.

It is worth recalling that Ricardo Teixeira has been elected to the FIFA Executive Committee by CONMEBOL (for the first time in 1994).
