Neymar was banned for insulting a referee and head-butting Colombia defender Jeison Murillo during Brazil's 1-0 defeat to Colombia in June. 

He was initially suspended for one game, ruling him out of Brazil’s third Copa América group game against Venezuela, but the punishment was increased following CONMEBOL's review of the case.

The Barcelona forward is currently banned from his country's first two World Cup qualifying matches against Chile and Venezuela, on October 8 and 13 respectively, having already missed two matches at the Copa América. 

The CBF's appeal challenges FIFA and CONMEBOL rulings that Neymar must serve the ban immediately.

CAS says the CBF wants the ban applied only at the next Copa América, which is scheduled to take place in the United States in 2016. 

A decision is due to be made before Brazil's World Cup qualification double-header next month. 

"In its appeal to the CAS, the CBF seeks to overturn the decisions taken by the FIFA Disciplinary Committee and the FIFA Appeal Committee which ruled that the two remaining match bans should be served during the next official FIFA competition," read a CAS statement.

"As all parties have agreed to an expedited procedure, the CAS will put in place a procedural timetable for this arbitration which allows for a decision to be issued to the parties by early October 2015."

Brazil’s quest for a ninth Copa América title was brought to an end in the quarter-finals after they suffered a penalty shootout defeat to Paraguay.  

Paraguay went on to lose their last-four tie against Argentina, who were beaten on penalties by host nation Chile in the final.
