WWE has removed Seth Rollins from the list of advertised Superstars on all of its live events between now and April 1, 2019.

Anyone who has bought tickets to a pro wrestling, boxing, or MMA show needs to be very aware of those four very important words. Card subject to change. WWE leans on this crutch more than most. Sometimes because it has to and other times because it makes their lives easier.

Sticking with WWE, we are now firmly on the road to WrestleMania. The time of year where WWE and its fans really don't want a reason to have to change the card. If an injury happens to a top star now it can potentially affect the entire WrestleMania card. That's why fans want to know whether Becky Lynch's knee injury is legitimate or merely part of an elaborate angle.

RUMOR: BROCK LESNAR WON'T COMPETE AT ELIMINATION CHAMBER OR FASTLANE

Annoyingly for WWE and the fans, Seth Rollins, the other 2019 Royal Rumble winner, is also rumored to be injured. The Architect hasn't done anything more than take six F5s from Brock Lesnar since winning the 30-man match. Rumors that he is apparently suffering with back issues have been furthered even more this weekend. The former WWE Champion has been removed from all live events on WWE.com between now and April 1, 2019.

April 1 is obviously the last Raw before WrestleMania, so if Rollins' match with Lesnar is going ahead, he will need to be on the PPV's go-home show. In addition to Rollins possibly not wrestling between now and his showdown with The Beast, WWE has also revealed that The Architect will be on Raw this coming Monday to address the Universal Champion. Perhaps this time Lesnar will attack him so brutally that we don't see Rollins for almost two months.

We don't know about the rest of you, but what we don't want WWE to have to do at this point is book on the fly. It made the right decision with both Royal Rumble winners this year. Rollins should be the man to dethrone Lesnar, and Lynch versus Ronda Rousey should main event WrestleMania. Sadly, no matter how much we want those matches, injuries might well change the course of history.
