The incident occurred after the final whistle, with captain Marllon and striker Alef Manga having a heated discussion inside the field.
Marcelinho, Remo's right-back, explained the team's struggles, saying: "We did a great first half, like we always do, but we alternate a lot between the times. Unfortunately, we took the goal there. It happened with the free kick, everyone is blaming each other, but unfortunately the result isn't coming."
Remo, who have now lost five consecutive games in the Brasileirão, remain in the penultimate position with 23 points.
The team will have almost two weeks of rest due to the FIFA date, before returning to action against Grêmio on the 7th of next month at the Mangueirão stadium.
