Lionel Messi Returns to Training Ahead of Crucial Copa América Quarterfinal

Messi's participation against Ecuador remains uncertain following recent injury recovery.

Messi resumed full training on Monday after a groin/thigh injury sustained against Chile.
He missed Argentina's final group stage game but the team won all three matches.
Argentina will face Ecuador in the quarterfinals on Thursday in Houston.
Messi has not scored in the tournament so far, a first in his Copa América career.
His status for the match is still day-to-day, with a possible bench role if he plays.
