It's good news, actually
Lionel Messi has been suffering for a while with some kidney stones. Now he's getting rid of them, and will have to miss a game in order to do so.
Barcelona's official website announced on Tuesday that the Argentine superstar has not trained with the squad in the last couple of days in order to deal with his kidney issues.
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.
