John Cena knee injury "a work"?

WWE superstar John Cena has reportedly not suffered a serious knee injury that could have ruled him out of Wrestlemania XXX.

Cena was left clutching his knee after a three-on-one attack from the Wyatt Family on Monday Night Raw, and it appeared that there was genuine concern at ringside as the 11-time WWE champion was stretchered to the backstage area.

A picture also appeared on social media of Cena's knee appearing to be out of place, but according to PWTorch.com, the "injury" to the 36-year-old is "a work", and he was not required to undergo an evaluation at a medical facility.

Cena is reportedly scheduled to face Bray Wyatt at the pay-per-view event at the Mercedes-Benz Superdome in New Orleans on April 6.
