WWE’s website has updated their official match preview for Sunday and it notes that Bryan is undergoing “diagnostic testing” to see if he’s able to perform. They wrote the following:
“Daniel Bryan rose above six other Superstars to capture his first Intercontinental Championship in a Ladder Match at WrestleMania. However, if the ever-popular “Yes!” Man hopes to hold onto the title, he’ll have to get past the Superstar who lost the championship that day, Bad News Barrett, at Extreme Rules. Bryan is undergoing diagnostic testing to see if he can defend his title at Extreme Rules.”
