Following his victory over the Big Show at Summer Slam, things came crashing down hard for Big Cass just 24 hours later.

During a Brooklyn Street Fight against his former Tag Team partner Enzo Amore on RAW, Cass would suffer a devastating knee injury.

The worst news for RAW

The injury occurred when Cass went to deliver a big boot to Amore on the apron but would instead go over the ropes and have a very awkward landing.

The seven footer would attempt to continue the match but that would prove to be impossible as the referee was forced to bring it to a premature end.

Awarding the victory to Amore was reportedly against the plan, but it was the only outcome when Cass was unable to even stand on his injured knee.

24 hours after suffering the injury, WWE have now confirmed the extent of it and it certainly bad news for the RAW roster.

"It looks like he has an ACL tear, possibly a medial meniscus tear, but we’re going to wait for the radiologist to evaluate the MRI and give us their full report,"

An ACL tear is one of the most feared injuries in all of sports and can result in a lengthy spell on the sidelines for athletes.

Ringside physician Dr. Chris Robinson was the man to provide the update and he claimed that a standard ACL tear often requires nine months to fully recover.

WWE confirmed on their website that Cass has suffered a major injury and will now require surgery as part of his rehabilitation.

In what could see him sidelined for up to nine months, the injury has come at the worst possible time for the New York native.

Possibly putting a potential return for Cass after WrestleMania 34, he could also be the big injury question ahead of the event in New Orleans in April.

The injury has come at the worst possible time for the man who has been rumoured to be receiving a singles push for several months.

Plans on hold?

Following his split from Amore, Cass was expected to receive a high mid-card push over the coming months and possibly even earn his way into a title picture, either the Universal or Intercontinental title.

Those plans are now impossible and it will be interesting to see if he is able to regather his momentum when he finally makes his return to WWE.
