Barcelona superstar, Lionel Messi has sustained an injury during training as the new La Liga season gets set to kick off.
Lionel Messi is set to miss Barcelona's upcoming trip to the USA after suffering a calf injury during his first training session back at the club, Goal.com reports.
Having been given extended leave following Argentina's run to the semi-finals at this summer's Copa America, Messi only returned to the fold on Monday.
However, he was forced to pull out of the session with what doctors have diagnosed as a grade one calf strain.
August has not been an easy month for Messi so far. Last week, it was announced that he would face a three-month suspension from international football plus a heavy fine after his controversial comments about perceived favouritism towards Brazil at the Copa America .
He joined back up with his club team-mates over the weekend and watched from the bench as they came from behind to beat Arsenal in what was the Gunners' final game of pre-season.
