The Brazilian defender may be deemed to have gotten away somewhat lightly after facing a disciplinary committee over the contract he made with an official
The Brazilian grabbed match official Peter Green during the Sky Blues' game at home to Melbourne Victory in Round 5, knocking a red card out of his hand as he attempted to dismiss Marc Warren.
Tiago, 32, was later banned for two games for striking Archie Thompson in the same match, which Sydney won 3-2.
However, he will sit out a further eight matches for a 'gesture' consisting of 'making deliberate contact with the referee' which was deemed 'at the very least offensive and insulting to his authority', according to an FFA disciplinary committee.
An additional four-match ban will be imposed if Tiago receives a straight red card at any stage during the remainder of the regular A-League season or finals campaign.
Comparisons have been made between the incident involving Tiago and the nine-month suspension, reduced from 12, imposed on Perth Glory's Danny Vukovic in 2008, with the crucial difference being that the Sydney FC man, as opposed to the goalkeeper, was not deemed to have struck a referee.
