Dylan Wenzel-Halls struck late with a thumping finish to end Brisbane's 12-match A-League winless run with a 2-1 victory over Sydney FC.
The 21-year-old sent the crowd at Suncorp Stadium into delirium on Friday with a smashing right-foot shot from the edge of the area in the 90th minute to secure the Roar's second win of a dismal season.
The victory will be especially pleasing for interim head coach Darren Davies given the lack of players at the Welshman's disposal.
Such was Brisbane's player crisis, Davies was forced to throw on schoolboy defender Izaack Powell in the 30th minute when Hingert limped off.
The teenager, who doesn't turn 17 until Tuesday, eclipsed Tommy Oar as the youngest player in the Roar's history when he came on.
It's Davies' first win since taking over following John Aloisi's departure just before Christmas.
The defeat will be desperately disappointing for Sydney coach Steve Corica, after his team had appeared to have wrested control from the dogged home team through De Silva's opener.
The visitors probably should have been ahead before De Silva found the back of the net, with Sydney guilty of wasting multiple first-half chances.
Milos Ninkovic had the best chance of the opening half but blazed over after being found unmarked just outside the six-yard box in the 21st minute.
The Roar face table-topping Perth Glory next weekend, with Spanish midfielder Álex López suspended after picking up his fifth yellow card of the season.
Sydney are at Leichhardt Oval next weekend to host bottom-placed Central Coast Mariners.
