When you work a job as physical as being a WWE superstar, injuries are expected, but just how many top-name wrestlers suffered injuries in 2015 proved a huge blow to the company.
There did not seem to be a point throughout the year where at least one of the biggest names in the business was being sidelined through injury.
Possibly the worst injury to have occurred during a live showing of WWE programming was when Sami Zayn made his emphatic WWE debut having come up from the NXT roster.

The moment couldn't have been more perfect for Zayn to take part in his first main roster match against the biggest name at the company; John Cena.
Hall Of Famer Bret Hart was on hand to introduce the 31-year-old to his hometown crowd, and Zayn proceeded to make his famous entrance.
This entrance in particular however, will now be remembered for Zayn suffering a serious injury to his shoulder, following throwing his arms up in the air so aggressively as he encouraged the crowd on the steel steps.
Both WWE and Sami Zayn will undoubtedly be looking for him to be making his mark once and for all on the main roster during 2016, as he will bounce back from this setback surely fitter than ever.
Another huge injury which took place in front of a live crowd saw then-WWE World Heavyweight Champion Seth Rollins fall victim to a very serious knee injury during his match with Kane in Dublin, Ireland.
Rollins was taking part in WWE's European tour when he tore several ligaments in his knee, which resulted in him being stripped of the biggest title in the business.
Following his absence, there was unquestionably a huge void which WWE needed to fill fast and which ultimately proved just how heavily the company relies on so few superstars.
Although no injury ever occurs at a good time for the WWE and its wrestlers, Rollins' came at one of the worst as Daniel Bryan and Randy Orton were already out of action as well as John Cena taking scheduled time off from the company.
These two examples combined with a number of injuries to other WWE superstars both minor and major throughout 2015, prove just how unfortunate the year was for the company and its talent with regard to injury.
With this in mind, 2016 should be seen as a comeback year and one which will produce a number of long-awaited returns which will hopefully result in a much more positive 12 months for WWE and its followers.
