The Limpopo-based club's demotion was confirmed on Saturday following a 1-1 draw against KwaZulu-Natal outfit Milford in the final promotion/relegation playoff fixture at their home ground.
The result saw the two sides exchange divisions, with Milford securing promotion to the top flight while Magesi dropped into the Motsepe Foundation Championship.
Dikwena tsa Meetse entered the decisive encounter knowing that only a victory would be enough to preserve their Premiership status.
They appeared on course to achieve that objective after taking the lead and carrying their advantage into the half-time interval.
However, Milford struck back after the break, finding an equaliser that ultimately proved decisive. The goal ended Magesi's hopes of extending their stay in South Africa's top division beyond two seasons.
Having finished 15th in the regular league campaign, Magesi were forced into the playoffs but were unable to secure survival.
"To Our Dikwena Family," Magesi's statement on X read.
"Saturday broke our hearts. And it hurts because it mattered most.
"This season was challenging. We faced setbacks, fought hard, and fell short of what we all wanted. Through every high and low, you stayed with us.
"Thank you for being with Magesi FC all season long. For the chants when our legs were heavy. For the belief when belief was hard. For wearing the Blue no matter what. You carried this club.
"Relegation hurts. But it doesn't change who we are. Dikwena Tsa Meetse. It's this community. It's you.
"This is a setback, not the end. We will rebuild and fight our way back. Because you deserve it. Because it matters most.
"From the players, coaches, and everyone at the club: Thank you for your love, patience and loyalty.
"Dikwena Tsa Meetse will rise again. Together."
