TRIPLE H INJURY UPDATE
According to WWE doctor Dr. Chris Amann, Triple H’s arm was placed in a hold that created a tremendous amount of torque on his upper arm and elbow.

“He has a non-displaced fracture of distal humorous,” said Amann. “Fortunately, this is not something that needs surgery with pins and screws. We’ll be treating him with a sling for comfort and following with him in the next few days.”
