WWE has posted another update on Shield member Dean Ambrose. They report that he had surgery on Tuesday night and it's currently uncertain how long "The Lunatic Fringe" will be on the sidelines.

The following comes from WWE.com:

Dean Ambrose underwent successful surgery Tuesday night to repair a high-grade triceps tendon injury, WWE.com can confirm.

The 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, and is expecting to leave Birmingham later today.

It is unknown at this time how long Ambrose will be out of action.
