As seen on last night's edition of Monday Night Raw, Dean Ambrose of The Shield appeared to have suffered some sort of legitimate arm injury.

The following comes from WWE.com:

DEC. 19 UPDATE: After sustaining an injury to his right arm last night during Raw, Dean Ambrose is currently undergoing further examination by noted orthopedic surgeon Dr. Jeffrey Dugas, WWE.com can confirm.

“An MRI has shown suspicion for a high-grade triceps tendon injury, possibly a tear, so he is undergoing surgical exploration and most likely surgical repair of the torn triceps tendon,” WWE Senior Ringside Physician Dr. Chris Amann told WWE.com. “That surgery will be happening later this evening, and we should have some further updates either later tonight or tomorrow morning as to what the findings were, what the structures that were damaged were, and also a timeline for recovery.”

Dean Ambrose sustained an injury to his right arm during Raw’s Six-Man Tag Team Match, and the damage was exacerbated when his opponents, Samoa Joe and Raw Tag Team Champions Cesaro & Sheamus, assaulted The Lunatic Fringe in the trainer’s room. The attack culminated when Joe slammed a road case onto Ambrose’s arm, leaving him writhing in pain.

Ambrose was taken to a nearby medical facility for X-rays and evaluation. Stick with WWE.com for further updates on his condition.
