Andres Guardado and Diego Reyes are among players who are in a race for fitness to make El Tri's final squad
Mexico manager Juan Carlos Osorio named a 28-man squad Monday of players still in consideration to make his final 23-man World Cup team.
The manager said he was hoping to call the 23-man squad, but five factors made him include five extra players.
Injuries to players that may not clear up before next month, players in leagues with remaining matches, a week-long rest mandated by FIFA after the players' final league match before joining up with the international squad, Mexico's game against Wales on May 28 and continuing to build competition in the squad have led Osorio to include five players he wasn't set to include.
