Fan violence reared its ugly head in Latin America once again as Palmeiras supporters attacked club players at an airport following the team’s 1-0 Copa Bridgestone Libertadores loss to Tigre.

Prass had to be treated for cuts to his head and ear, but no one was seriously hurt in the altercation before the team’s return to Brazil. Palmeiras said three fans were detained in Argentina but were later released.

”They threw a cup at Valdivia and it hit me,” Prass said through his Twitter account. ”I got three stitches in the head and a cut in my ear.”
