In a match that had become contentious after a series of late fouls, the teams were working to separate after a small scrum on the sidelines when Kaka reached around Collin from the behind, putting his hands on the face of the defender in process.
Referee Jorge Gonzalez took to video review to determine what exactly happened and decided on handing out yellow cards to Cristian Higuita of Orlando and Sean Davis of the Red Bulls, who were both directly involved in the play leading to the sideline scrum, but issued Kaka a straight red card for violent conduct.
Collin and Kaka can both be seen laughing the incident off, however, and it even appears as though the defender may have tried to come to the defense of his former teammate.
New York took a 3-1 win in the match, and the sending off came in the dying moments. MLS will review the incident and may well void any future punishment, but the decision to send off Kaka will certainly raise more questions about how video review will impact matches going forward.
