(CNN) -- Saudi Arabia's quest for a fourth Asian Cup title, and first since 1996, is over after they slumped to a 1-0 defeat at the hands of Jordan in Doha on Thursday. 

A mistake from goalkeeper Waleed Abdullah sealed Saudi Arabia's fate, as the kingdom slumped to their second successive defeat following their surprise 2-1 loss to Syria on Sunday. 

Last weekend's defeat saw the instant dismissal of Portuguese coach Jose Peseiro, but his replacement Nasser Al Johar failed to get the victory the Saudi's needed to keep their tournament alive, despite making four changes to his side. 

An ominous sign for the 2022 World Cup? 

The only goal of the game came three minutes before half-time against the run of play. 

There looked no danger when Baha Abdelrahman floated in a cross from the right hand side, but Abdullah completely misjudged the flight of the ball and could only watch on in horror as it looped into the net. 

Despite the shock nature of their exit, Al Johar was philosophical about the defeat. "We played very well and we created opportunities to score, especially in the second half," he told reporters. 

"But we were not lucky and this is football. Maybe we'll do better in the future," he added. 

The result means Saudi Arabia become the first team to bow out of the competition and puts Jordan level on points with Japan at the top of the group. 

Meanwhile, Group B favorites Japan claimed a hard fought 2-1 win over Syria in the day's other match to move onto four points after their two matches.
