Judd, who turned 26 on Tuesday, had been offered a two-match suspension if he took an early guilty plea to the charge of making unreasonable and unnecessary contact to the face of Brisbane Lion Michael Rischitelli at the Gabba on Saturday night.
But Carlton elected to take the case to the tribunal, and Judd will now sit in the stands for an extra week.
"Obviously I'm disappointed with the outcome but now we'll go and assess our options and we'll make further comment at a later date," Judd said after the hearing.
Judd was charged with eye-gouging in 2007 after the West Coast Eagles played Hawthorn in Tasmania but was found not guilty, although the alleged victim, Campbell Brown was later fined $15000 after he admitted lying to an AFL investigator about the incident.
When asked if it was rather unusual to be involved in a second eye-gouging case, Judd dismissively replied: "Oh yeah" as he left the tribunal.
Football manager Steven Icke confirmed that the club would look at all options in relation to an appeal.
Judd, who is equal third favourite for this year's Brownlow Medal, can still win the competition's best and fairest award because the report came from a final rather than a home and away game.
The Blues tried to get the level of impact reduced from low - the lowest level - to negligible, and thus have the charge dismissed, in the process urging the jury to ignore the hysteria from the media regarding the incident.
However, AFL counsel Jeff Gleeson SC said in his summing up that "it looked like a player searching around a face" in relation to Judd's left-hand actions, and questioned why Judd had made contact with the head at all.
After over an hour for the hearing, the jury took just six minutes to return the guilty verdict.
Carlton's counsel, David Grace QC, then attempted to argue that the jury was able, in "exceptional and compelling circumstances", to reduce the penalty, and that this case fitted that description due to the level of force shown on the instructional DVD issued by the AFL to show the various charges and levels of impact not relating to this incident.
But that argument was dismissed after just a couple of minutes' deliberation by the jury after Gleeson warned of the dangers of second-guessing the AFL Commission, which had ratified the penalty table.
Judd gave evidence during the hearing, and said that his statement on returning to Melbourne about looking for a pressure point had been a "poorly-timed joke" as he tried to make light of the situation after half-an-hour's sleep due to the players having an impromptu party at a Brisbane bar after the loss to the Lions ended their season, and with just one minute's warning about the media conference on entering the airport terminal.
Judd, a former West Coast captain, said the comment came from a running joke among Eagles players about how WWE wrestlers - entertainment much enjoyed by the players - would apply the sleeper hold.
He also said that he was attempting to hold down Rischitelli's head to get him off teammate Shaun Grigg, but that the humid nature of a Brisbane night had left the Lions' player's head "sweaty and slippery", but admitted that to touch the face at all was "simply a mistake".
