Lionel Messi took part in Argentina’s training session in Houston, Texas, on Wednesday ahead of their Copa América quarter-final against Ecuador.

Earlier, coach Lionel Scaloni announced that Messi is still uncertain for the match at the NRG Stadium in Houston.

Messi suffered a right hamstring injury during the match against Chile and did not play in the final group stage match against Peru. Scaloni was also absent from that match, serving a one-match suspension imposed by CONMEBOL.

Reigning champions Argentina are aiming for a record 16th Copa América title. They will face Ecuador, who secured their place in the quarter-finals by finishing second in Group B after a straight draw with Mexico.
