Former Argentina captain Javier Mascherano could miss Tuesday's key World Cup qualifying clash versus Colombia as he struggles with a calf injury sustained against Bolivia.
The Barcelona midfielder was taken off in the final minutes of Friday's 1-1 draw complaining of severe cramp in his right leg. Ole subsequently reported that in the first training session on Sunday prior to the Albiceleste arrival to Barranquilla, Mascherano played no part.
The player was replaced by Estudiantes' Rodrigo Brana in the first team as Alejandro Sabella put his men through their paces, and the coach is yet to confirm whether he will recover in time for the meeting with the Cafeteros. An announcement is expected on Monday evening, when Sabella addresses the press.
Argentina are expected to make three changes from the line-up which drew against Bolivia at home, and that could rise to four if Mascherano is ruled out.
Napoli defender Federico Fernandez will replace Martin Demichelis in the centre of defence after the Malaga man drew all the flak for his disastrous error that led to Bolivia's goal. Ricky Alvarez and Javier Pastore were also retired from the starting line-up during the practice session, replaced by Pablo Guinazu of Inter and Jose Sosa as Sabella considers reverting to a more conservative 4-4-2 system.
