Lionel Messi to be treated for kidney stones but unlikely to miss Barca game

Lionel Messi will undergo a medical procedure for kidney stones on Tuesday but the Barcelona star is not expected to miss Wednesday's match against Valencia because of the treatment.

The 28-year-old was sidelined by kidney stones during the Club World Cup semifinal this past December, and he did not train on Monday because tests had detected more kidney problems.

A club statement read: "FC Barcelona striker Lionel Messi will undergo several tests on Monday and Tuesday to assess the evolution of the kidney problems he suffered last December. Messi will return to his normal duties with the first team on Wednesday."

According to Mundo Deportivo, the Argentina international will be treated at the Dexeus university hospital in Barcelona, where he will receive shock wave lithotripsy, a non-invasive treatment that breaks up the stones into tiny pieces.

Barcelona travel to Valencia on Wednesday for the second leg of the Copa del Rey semifinals, though Messi is unlikely to be needed with his side holding a 7-0 advantage from the first leg.
