"Doctors expect to keep him there for the next few days for further diagnosis and observation while anti-biotic treatment continues," the statement read, noting that a full recovery is expected over the next few weeks.
The news comes on the heels of the announcement earlier this week that Adam "MCA" Yauch of the Beastie Boys will be undergoing treatment for cancer of the salivary gland in his throat. That treatment knocks the Beasties out of four major summer-festival dates, including Lollapalooza (August 7-9), where the Yeah Yeah Yeahs will take their place. Jane's Addiction, whose singer Perry Farrell is one of the co-founders of Lolla, are also slated to headline one of the nights of the upcoming festival on the Chicago waterfront, and a spokesperson for the group said Perkins' hospitalization is not expected to impact the group's Lollapalooza performance in any way.
The Australian tour by the indie-rock godfathers — who reunited with their full original lineup last year and are in the midst of their first world tour together in more than 17 years — was due to kick off Saturday. "I know how excited we were to come play in Australia, and how long the fans there have waited for this," Farrell said in the statement. "I want everyone Down Under to know that we will come back as soon as we can."
The band had recently returned to Los Angeles after a European leg of the tour when an unidentified infection was discovered after Perkins noticed severe swelling and pain in his elbow.
