Song was given his marching orders for a shocking elbow on Croatia striker Mario Mandzukic, leaving referee Pedro Proenca no option but to show a red card to the former Arsenal midfielder.
Cameroon were already facing a humiliating end to their tournament as Croatia threatened to run riot, winning 4-0 with Mandzukic grabbing a brace.
But as the game reached its closing stages, Cameroon's tournament descended further into chaos when Tottenham left-back Assou-Ekotto became embroiled in an on-pitch argument with team-mate Benjamin Mounkandjo.
The 30-year-old appeared to be unhappy with Mounkandjo's part in Croatia's fourth goal and confronted him on the pitch. Remarkably, as Mounkandjo gestured for him to leave him alone, Assou-Ekotto appeared to headbutt the striker, sparking incredible scenes.

Assou-Ekotto had to be restrained by captain Samuel Eto'o as the teams headed down the tunnel, and coach Volker Finke blasted the "disgusting" behaviour of his players.
"It's unimaginable," said Finke. "I saw this happen and I need to find out exactly what happened, why exactly these two players exploded.
"It's clear we have to find the reasons what's going on because such behaviour is really disgusting, it won't do, it's impossible."
Song later apologised for his part in the off-the-ball scuffle with Mandzukic which resulted in the Barcelona man heading back to the changing rooms for an early bath.
In a statement the 26-year-old said: "I'm very sad at the moment as I feel I have let my country and myself down.
"It was a stupid moment and I'm truly sorry. If I could do anything to take it back I would. Please forgive me."
