Pro Wrestling Sheet has learned Kalisto has been out of action as of late due to injury.

According to sources, the Lucha House Party member suffered a shoulder separation that does not require surgery at this time. It's unclear, however, how long he'll be unable to wrestle.

While we don't have official confirmation on when the injury occurred, it would appear as though it happened during a live event at the Staples Center in December. The wrestler's match that night against The Revival ended abruptly and Kalisto was checked out by WWE's medical team afterward.

As we previously reported, the 33-year-old wrestler recently signed a new WWE contract.

We here at The Sheet wish Kalisto a speedy recovery.
