It was previously reported that WWE Raw Superstar Dean Ambrose of The Shield might only have to miss a few months of action after his recent arm injury. However, WWE is now reporting that the WWE Grand Slam Champion could be out of action for up to nine months. If true, this would mean that not only will he be missing WrestleMania 34, but he could also miss the 2018 SummerSlam pay-per-view as well.

The following comes from WWE.com:

Following Dean Ambrose’s successful surgery last Tuesday night to repair a high-grade triceps tendon injury, Michael Cole took a moment during the Dec. 25 episode of Raw to confirm that The Lunatic Fringe will be out of action for approximately nine months.

Ambrose’s successful procedure was performed by Dr. Jeffrey Dugas in Birmingham, Ala., and took around 40 minutes.

“He tore some of the distal triceps tendon where it attaches to the forearm bone, called the olecranon,” Dr. Dugas told WWE.com. “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.”

Dugas added that Ambrose has begun physical therapy, starting with light range-of-motion exercises.
