A Brazilian footballer plummeted down a tunnel in frightening fashion during a match, only for his goal to be disallowed.

The incident occurred when Coritiba hosted Chapecoense in Brazil’s top flight on Saturday.

Coritiba defender Jacy thought he had scored to put his side 2-0 up in the first half, with the 29-year-old jumping over the advertising hoardings in celebration.

Unbeknownst to Jacy, a tunnel leading to the dressing rooms had been uncovered in preparation for half-time.

Jacy ultimately fell straight down the hole and into the tunnel, with a horrified security guard seen sprinting down the stairs to attend to the defender.

Anxious Coritiba team-mates were seen peering over the advertising hoardings to check on the condition of their team-mate.

Jacy returned following the fall and received treatment from Coritiba's medical staff.

The incident became more painful for the Brazilian after his goal was ultimately ruled out for offside following a VAR review.

Jacy was able to continue the match briefly but was forced off two minutes into the second half as the defender continued to feel the after effects of the fall.

Remarkably it was not the first time a player has fallen down the tunnel at the Couto Pereira stadium.

Back in 2014, Coritiba striker Joel fell down the open tunnel as he celebrated one of his two goals in a match against Sao Paulo.

The same security guard who attended to Joel was also on hand to provide Jacy with assistance.

Coritiba recorded a 2-1 victory over Chapecoense on Saturday despite Jacy's goal being disallowed.

The match did see a more serious medical incident with Chapecoense midfielder Max Alves having been taken to intensive care after colliding with his own team-mate.

Alves underwent surgery to have a chest drain inserted, with the Brazilian having also been diagnosed with multiple rib fractures following the incident.
