Atlanta Silverbacks defender Mario Pérez Zúñiga has been registered by the Mexican Primera Division's Estudiantes Tecos, making him eligible to play in Mexico's top soccer league in its upcoming season. Perez last played in Primera with Necaxa in 2009 -- though league rules give his former team first rights upon his return, Necaxa transferred those rights to Estudiantes Tecos.
The 2011 season was Perez' first in the NASL, where he's contributed a goal and three assists in his 10 appearances, including an assist in the team's victory over the MLS-bound Montreal Impact. He's unavailable to play for the Silverbacks as of their upcoming game against FC Tampa Bay.
He's played three different stints with Necaxa since turning pro in 2001, also playing for Club América, San Luis F.C., Club Atlas and a handful of Mexican national teams including the 2004 Olympic side and the 1999 U17 squad.
