The 31-year-old forward, who plays for Russian club Spartak Moscow, was arrested in December 2020 regarding the incident which happened in July of that year.
The court in the Netherlands found charges of assault against Promes proven, but found there was no attempted murder or manslaughter, according to ESPN.
He must pay €7,000 [£5,973] in compensation to the victim. Promes is also being prosecuted in the Netherlands for alleged involvement in drugs trafficking.
He is suspected of being involved with smuggling 1,360 kilograms of cocaine to the Netherlands or Belgium in two shipments in 2020.
Promes, formerly of Ajax, denied the charges but the court found there was enough evidence from two eyewitnesses and intercepted phone conversations to hand down a prison term.
The stabbing, to the leg, occurred at a family party at a warehouse in Abcoude after Promes got into an argument over a stolen necklace. He was playing in the Netherlands for Ajax at the time but moved to Spartak in February 2021.
The judge criticised Promes, who is currently in Russia, for not coming to the court to defend himself or expressing any remorse.
His sentence would have been six months less had he done so. Promes can appeal the conviction.
