It couldn't come at a worse time, but just as Sin Cara was looking to receive a decent push on SmackDown Live, the recently re-signed WWE Superstar might be on the shelf for a while.
At a WWE Live event in Madrid, Sin Cara was in a match with Sami Zayn and Baron Corbin and he ducked awkwardly to avoid a Corbin clothesline. As he went down, his own leg bent under the weight of his and Corbin's body and you could tell immediately that Sin Cara was hurt. The referee came over to check on him and the match ended early with Sin Cara being helped to the back by WWE officials.
It's difficult to make out the severity of the injury from the video but you can see the moment Sin Cara goes down. He immediately grabs his knee and can't continue the match. Sami Zayn tries to encourage Sin Cara to continue but after realizing there's a problem, calls Corbin into the ring to go a different direction.
If you take a closer look via the photo below, you can see just how badly Sin Cara bends his leg. Warning, the photo is not for the weaker stomachs out there.

How long Sin Cara will be out of action is unknown at this time. Hopefully, it's not anything too serious, but if it is, it's the worst possible timing for the masked wrestler.
He's been largely irrelevant for months on WWE programming and just recently his career has been renewed in a feud with U.S. Champion, Baron Corbin, including some surprising wins over the "Lone Wolf". If Sin Cara misses any lengthy amount of time, it's hard to say where that puts him in terms of his current push.
The WWE Universe can only hope for his sake that he'll be back and that this knee injury is only a small injury that forced him to end the match and not something long term that could affect his career.
