Blumenau EC suffered a narrow 1–0 home defeat to Marcilio Dias SC in Brazilian Serie D action on May 17, 2026, at Estádio do Sesi. The result extends Blumenau's winless streak to four matches, while Marcilio Dias leapfrog their opponents in the group standings.

First half: a tense stalemate

Both sides struggled to create clear-cut chances in a tightly contested opening 45 minutes. Blumenau EC enjoyed the majority of possession but lacked the final ball to unlock a well-organized Marcilio Dias defence. The visitors, content to sit deep and counter, registered only one shot on target before the break – a speculative effort from distance that was easily gathered by home goalkeeper Felipe.

Second half: Marcilio Dias strikes the decisive blow

The delivery was swung into the box, and after a goalmouth scramble, forward William prodded the ball over the line from close range. Blumenau pushed for an equaliser, introducing fresh legs and switching to a more direct approach, but the Marcilio Dias backline held firm. The hosts came closest in the 78th minute when a header from Carlos rattled the crossbar, but the rebound was cleared to safety.
