World Wrestling Entertainment (WWE) superstar Dean Ambrose will be out for nine months after the wrestler injured the triceps muscle on his right arm.

Ambrose, 32, legitimately injured his arm during a six-man tag with his "Shield" allies Roman reigns and Seth Rollins against Sheamus, Cesaro and Samoa joe.

During the match, Rollins leapt out of the ring and landed on Cesaro and Samoa Joe, who were ganging up on Ambrose. Unfortunately, Rollins' maneuver went awry and he ended up hitting his teammate as well. The referee immediately called for medical staff to check on Ambrose, who was clutching his arm and seemed to be in tremendous pain.

Ambrose was then brutally assaulted by Joe and the others backstage, but this was done in order to cover the injury and write the wrestler off on television for a while, as he clearly needed intensive treatment.

Dr. Chris Amann, senior ringside physician of the WWE, said that Ambrose might have a high-grade tear in his tendon. "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," Amann said, according to a report posted on WWE. 

During the Christmas day episode of "Monday Night Raw," Michael Cole announced that Ambrose will be out of action for nine months, meaning the superstar will not be expected to return until September. This also means that he will be missing "Wrestlemania 34" in April 2018.

Ambrose, known in real life as Jon Moxley, has already undergone surgery for his arm in Atlanta. The procedure was successful and lasted for 40 minutes.

Dr. Jeffrey Dugas, who performed the surgery, confirmed earlier suspicions that Ambrose had torn the tendon on his triceps. "He basically tore about 50 percent of the triceps tendon away from the bone. So yesterday we repaired that back down to the bone where it tore off of. The surgery was very straightforward; we removed all of the extra bursal tissue — all of that extra swollen stuff around his elbow," he told WWE. 

Ambrose is already undergoing physical therapy to begin his recovery.
