On Sunday 12th August, Fox collapsed during a gig in Las Vegas playing for another band and was taken straight to hospital.
The Californian band Stryper released an official statement, saying: "After performing an MRI, doctors discovered an area of concern near his brain which they are now running a biopsy on. The doctors have instructed him not to drive or fly for 90 days. No additional information is available at this time. We appreciate your thoughts and prayers and we will communicate additional information as it becomes available."
They add that he still plans to tour with them but in the meantime a Go Fund Me page has been set up by his wife, Annie Lobert, as he doesn't have health insurance.
The page says: "We don't know how much the brain biopsies will cost, nor what will happen when we get the results back--whether he will need more surgery to remove any tumors or treatment plans for healing."
Annie Lobert wrote on facebook that "this has messed me up!" but added that she was reminded of 2 Chronicles 20: "Do not be afraid nor dismayed because of this great multitude, for the battle is not yours, but God's."
Lobert appealed to his fans: "So here is what I'm asking all of you to do—believe that God is good—worship with us & pray with us as we head into this battle.
"We trust God no matter what. This is how we fight our battles—it may look like we're surrounded but God is surrounding us.
"Oz says he just wants to get home & play his guitar—get better & get back on stage."
Stryper formed in 1983, making music that was openly Christian and receiving mainstream success, being the first band to ever have two songs in MTV's Top 10 simultaneously with their hits "Free" and "Honestly."
