DevilDriver guitarist Mike Spreitzer will be sitting out the band's tour of South America, as he suffered a seizure earlier this week while preparing for the kick-off of the six-date trek.

The band alerted their fans of Spreitzer's condition Monday via their Facebook page, stating: "Mike Spreitzer was hospitalized this afternoon (he has now been released and is okay) but unfortunately he will not be joining the band on their South American tour as doctor's have ordered him not to. The tour is still continuing. Please head over to Michael Spreitzer's page and send him your well wishes."

Spreitzer took to his Facebook page soon after to update concerned fans who heard about the seizure. "Hey everybody. Thank you all so much for your concern," he wrote. "It means so much to me. I'm doing okay and I'm back home. I'm not sure why, but I had a seizure in a Rite Aid while I was picking up a few last minute items for our South American tour. I collapsed and hit my head fairly hard."

He continues, "But the good news is all the tests results and cat scan came back negative. So, I've been ordered to rest and stay home. I'll be up and running for the next tour with Arch Enemy. I'm so upset that I can't go to South America. I was so excited. Thanks again for your concern and I love you all."

Jeff Kendrick is slated to be the sole guitarist for DevilDriver's tour of South America and Mexico, which is scheduled to kick off Wednesday, Aug. 10, at Teatro Flores in Buenos Aires, Argentina.
