Papa Roach fans are definitely a little concerned as the band has just bowed out of their South American tour, citing vocal issues for frontman Jacoby Shaddix. You may remember that the band missed a good portion of road time last summer when Shaddix was diagnosed with a nodule on his left vocal chord.

This time around Shaddix is suffering from strained vocal chords and has been ordered by a physician to undergo strict vocal rest. The band apologized for their newly missed dates, and plan to reschedule the South American shows for next year.

Guitarist Jerry Horton said in a Facebook post:

To our fans in South America, we are sorry to say our tour is canceled. Jacoby is having vocal issues, and has been ordered to rest. We will be rescheduling the tour for next year.

The four-date trek was scheduled to hit Sao Paulo, Curitiba, Buenos Aires and Santiago between Aug. 7-14. There was no word on whether or not Shaddix's vocal issues would affect the band's standing on the Carnival of Madness tour, which is expected to start later this month.
