VIDEO: Neymar, Bacca shown red cards for involvement in fight after Colombia's victory over Brazil

Brazil's aspirations to claim the 2015 Copa America title likely just took a massive hit, and not because of losing Wednesday's contest against Colombia.

Upon the final whistle of Los Cafeteros' feisty 1-0 win at the Estadio Monumental David Arellano, Brazilian captain Neymar appeared to headbutt defender Jeison Murillo seconds after smashing the ball into Pablo Armero's back.

Those petulant acts incited Carlos Bacca to come flying in and escalate the situation by delivering a swift two-handed shove to Neymar from behind, which resulted in both men being shown straight red cards as they walked off the pitch.

The red cards will see both men suspended.

While Bacca will likely serve a one-match ban, Neymar could be facing at least two games on the sidelines. The Selecao's star attacker was already set to miss his team's group finale against Venezuela after receiving his second yellow card in as many matches earlier in Wednesday's game.

Tacking on the red he was shown for the apparent headbutt, it seems likely that Brazilian manager Dunga will be without his undisputed best player for two matches.

For a team that has become almost entirely dependent on the sinewy No. 10 to carry the bulk of the attacking responsibility, this could prove a fatal blow for a side that came into this tournament expecting nothing less than a title.
