To answer your question in your title, Yes I’m surprised. To answer the question in your post, no I don’t think he deserves to be co-main. Back injuries generally don’t get better especially when you’re in the hurt business. I thought he got a stem cell treatment originally but he said in an interview that it was, I’m assuming, caudal steroid injections or facet blocks. He said his discs were intact and it was purely muscular impingement but it seems like an awful big risk putting him as co-main.
