Lionel Messi trained alone on Saturday as Argentina continued their preparations for their Copa America Centenario opener against Chile.
Albiceleste captain Messi had to be substituted after sustaining a knock to his back during his country s friendly against Honduras last week, sparking fears he may not be fit in time for Monday s re-run of the 2015 Copa final in Santa Clara.
Messi is back with Gerardo Martino s squad in California after returning to Barcelona to give evidence in a tax fraud trial against him and his father in midweek, but the Ballon d Or holder was unable to train with his team-mates.

A statement on the Argentine Football Association s official website read: Lionel Messi and Lucas Biglia trained separately, while Javier Pastore and Ezequiel Lavezzi participated in the group play with a ball and then practiced apart.
It remains to be seen whether Messi will take part in Sunday s final training session before the Chile match.
