East Kilbride have been awarded a 3-0 win over Kilmarnock after the Ayrshire club played an ineligible player in Saturday's Scottish League Cup tie.
The Scottish Championship outfit, who had admitted an "inadvertent" breach of SPFL rules, were also given a £5,000 fine, suspended until 30 June, 2022.
Daniel Armstrong was used as a substitute in Kilmarnock's 2-0 victory but was serving a one-game suspension.
The 23-year-old winger was making his debut after joining from Raith Rovers.
He had replaced Chris Burke after 72 minutes, at which point the Lowland League hosts were already two goals behind.
The award of a win lifts East Kilbride to the top of Group G with four points from two games and sends Tommy Wright's side to the bottom with no points from their only match so far.
Kilmarnock, who were also reprimanded and warned about their future conduct at Thursday's SPFL tribunal, said they "reiterate our apology to our fans, as well as East Kilbride and the footballing authorities".
They added: "While processes are already in place to try and prevent something of this nature occurring, clearly mistakes can and have occurred in this case.
"After quickly investigating the circumstances, we have immediately added an additional step to our internal procedures to ensure this cannot happen again."
Speaking on Friday, manager Tommy Wright added: "It's one of those things, we hold our hands up to it, we made a mistake.
"We aren't disappointed because we still won the game and put in a good performance. We just have to take that into the next three games."
Armstrong will serve his suspension on Saturday as Kilmarnock visit Clyde, the League 1 side having won their opening game against Stranraer.
