Daniel Bryan stating last night at the WWE Money in the Bank PPV that he may need a second surgery on his neck is said to be the truth according to a report by Mike Johnson. Bryan has not seen strength return in one of his arms since the initial surgery he had on his neck back in May and at times, that arm has seen its strength even weaken from where it was prior to the surgery. Bryan is currently undergoing physical therapy, but if the therapy is not enough and if Bryan needs to undergo a second surgery on his neck, Bryan could be at for at least another 6 months, depending on the procudere he undergoes.
