Argentina's Superclasico descended into chaos as five players were sent off in River Plate's 1-0 off-season 'friendly' win over Boca Juniors.
Boca were down to eight men by the 78th minute, before River's Jonathan Maidana, for headbutting Carlos Tevez, and Leonardo Pisculichi saw red.
"Neither of us behaved well," Tevez said referring to himself and Maidana.
Pisculichi scored the winning goal from the penalty spot in the 17th minute after Tevez had handballed.
League champions Boca also had two players sent off in the 4-2 defeat by Racing Club in Mar del Plata in midweek.
"In four days, five sent off, in two matches, we must grow up," the former West Ham, Manchester United and Manchester City forward added.
- Jonathan Silva, 10 minutes into his debut, for a lunge on Gabriel Mercado
- Gino Peruzzi for a foul
- Daniel Diaz for insulting referee Patricio Loustau
- Maidana dismissed for headbutting Tevez
- Pisculichi for getting involved in the resulting melee
