A week after WWE superstar Seth Rollins said he legitimately hurt his knee during a scripted scuffle with Samoa Joe on “Raw,” the pro wrestling company confirmed the injury as a torn medial collateral ligament.

“Because of Joe’s attack — Seth Rollins tore his MCL in the attack — his participation in WrestleMania is in serious doubt,” announcer Michael Cole said during Monday’s “Raw.”

This is the second year in a row the 30-year-old, whose real name is Colby Lopez, may have to miss the pro wrestling world’s most prestigious event. He missed last year’s WrestleMania because of the same knee after suffering a torn anterior cruciate ligament, MCL and meniscus during a match in Ireland in November 2015. The wrestler was forced to forfeit his title afterward while he took eight months to recover from surgery.

According to Wrestling Observer’s Dave Meltzer, Rollins is expected to need just six to eight weeks to recover from his latest injury, but that would put the wrestler just on the cusp of being able to perform at WrestleMania 33 on April 2.

On Tuesday, the star took to Instagram to express a new message of endurance.

Quoting from the Chuck Palahniuk novel “Fight Club,” Rollins posted a throwback picture of himself and current nemesis Triple H and wrote, “Without pain, without sacrifice we would have nothing. Like the first monkey shot into space.”

Rollins’s latest missive follows a short essay he penned in a series of tweets last week, in which he said his injury “is real” and admitted “a lot is up in the air right now.”

“Wanted to take a second to thank everyone who has reached out to me over the last two days,” he wrote last Wednesday. “Life doesn’t always go your way, but that is no excuse to surrender. If anything, obstacles exist to help us grow and evolve.”

Rollins continued, insisting that despite his injury, “one thing remains constant.”

“My resolve,” he wrote. “This doesn’t end for me until I’ve reclaimed the throne.”

Rollins’s injury occurred in the closing minutes of “Raw” last Monday, while WWE attempted to further his feud with Triple H, whom he likely would’ve faced (and still could face, depending on his recovery) at WrestleMania.

It isn’t exactly clear what happened to injure Rollins’s knee, however, he took several large bumps after being ambushed by Samoa Joe in the segment.

As it is with pro wrestling, deciphering the truth took longer than normal as some speculated the injury was fake and part of the planned story line following a tweet posted by Samoa Joe on Wednesday.

However, shortly after Samoa Joe posted his tweet, Rollins followed up with a photo of what is presumably his knee strapped into a rehabilitation device.

Despite the injury, Rollins is sticking with the story line.

“I will work harder than I ever have and push myself beyond what I know,” he said on Twitter last week. “This isn’t over. The only way to wear the crown is to slay the king. I know what must be done and there’s nothing that can stop me. … Fighting and defeating Triple H is the only way.”
