Former England manager Fabio Capello is willing to testify on John Terry's behalf at the defender's Football Association hearing.
Capello and his former assistant Franco Baldini, who was also prepared to travel to London, have provided statements instead of flying in.
The hearing will go into a fourth day and Terry, who was accompanied by Chelsea chairman Bruce Buck throughout the day, left Wembley shortly after 1600 BST on Wednesday.
Capello and Baldini were contacted by Terry's lawyers ahead of the FA's independent regulatory commission.
Reports suggest Terry's lawyers want the FA charge against the former England captain dismissed because he was found not guilty of a racially aggravated public order offence at Westminster Magistrates' Court in July.
Two weeks after being cleared, the FA charged Terry with using "abusive and/or insulting words and/or behaviour" towards Ferdinand during October's Premier League game at Loftus Road.
Capello resigned as England manager after Terry was removed as captain without his agreement.
