Panama's final World Cup warm-up match ended in defeat as the minnows were beaten 1-0 by Norway in Oslo.
The upcoming tournament in Russia will be Panama's first appearance at world football's showpiece event, but they head into it having only won one of their last seven matches.
Joshua King's strike – his second in as many games this month – was the difference at the Ullevaal Stadion, the Bournemouth striker firing Norway ahead in the fourth minute, holding off two defenders before poking past Jaime Penedo.
Substitute Gabriel Torres wasted Panama's most promising second-half move as he dragged a shot wide from 12 yards, leaving the visitors without a goal in both friendly matches before heading to Russia.
Ola Kamara should have doubled Norway's lead late on but he inexplicably blazed over from close range after excellent work by Crystal Palace striker Alexander Sorloth.
