It's been a really bad day for WWE's favorite fella, Sheamus. The Celtic Warrior hasn't been seen on WWE programming since suffering an injury on the November 17 episode of Monday Night Raw when he, Rey Mysterio, and John Cena defeated The Judgment Day in a six-man tag match. Sheamus suffered a shoulder injury in the match and needed to be removed from Cena's "Last Time is Now" tournament. He would eventually undergo surgery at the end of 2025.Last week, Sheamus posted some images from the WWE Performance Center after completing some in-ring work. These images led fans to believe his return to the company was imminent. Unfortunately, a new gruesome injury might end up delaying those plans.
