He was always suspended from the LC Final, a booking in the Semi Final took him over the limit.
It is not clear which two games the ban would relate to.
In Warren's case, it was the next two games (but that was a league game). When McCulloch was cited and banned, his two games were the next game in any competition, and the next Scottish Cup game.
In either case, this would mean Ciftci missing the two Celtic games after the LC Final - the first is a Cup game so if the ban had a Scottish Cup element that would cover that, meaning the Celtic league game would be the next game in any competition. As these are the next two games he is available for, those two games would be covered by the next two games outcome.
The current SFA disciplinary rules are difficult to fathom at times, and I can't find them published anywhere (they used to be on the SFA website, but I can't seem to find them). It would help if the published them for all to see, and so we would only need to speculate about whether the punishment will actually be, rather than how it will be served.
