Jamaica coach Winfried Schafer claimed his team would "protest" some of the cards given to his team on Tuesday, and revealed goalkeeper Dwayne Miller was taken to hospital.
Miller was substituted in the 24th minute after suffering a head injury in Toronto but Jamaica went on to win 1-0 over El Salvador to top Group B at the 2015 CONCACAF Gold Cup.
"We have to talk. We have 24 hours to protest," the German coach said, according to the Jamaica Gleaner.
Speaking about Miller, who was replaced by Ryan Thompson, Schafer said: "Miller is in hospital and I hope all the best for him."
"We were massive underdogs coming into this tournament," goal-scorer Garath McCleary said.
"To come out on top is fantastic."
Schafer added: "I'm very, very happy about my team. I trust my players.
"Everybody fights together, all for one, and I'm very happy, very proud of my players."
