Joel Peralta (virus) is expected to be placed on the disabled list. Peralta believes that he acquired the chikungunya virus, an illness transferred by mosquitoes in the Caribbean, which is where Peralta spent his All-Star break. He would be placed on the disabled list retroactive to July 13, setting him up to return within a few days assuming he feels up to it. Jeff Beliveau is the most likely replacement on the active roster.
