Wrestling Legend X-Pac Tore His Bicep In Tag Team Match Last Month, Needs Surgery

Crushing news for X-Pac ... the former WWE superstar says he tore his bicep last month in his highly anticipated return to the ring, and will require surgery to fix the injury before getting back in the squared circle.

49-year-old Pac, government name, Sean Michael Waltman, posted the gruesome pic of his injury on Twitter and an update on his health status, and it was pretty tough to digest.

"I tried to keep this on the down-low," X-Pac wrote, "but I tore my bicep in the tag match a month ago."

"I'm going to have surgery soon & then have a few more matches."

Pac joined the "TMZ Sports" TV show (airs weeknights on FS1) last month ... and told Mike & Mojo he was returning to the ring after a 3-year layoff to resume his wrestling career.

Sean announced that he would be fighting under the independent wrestling promotion Game Changer Wrestling, and his first match would be a tag team match.

The 2x WWE Hall of Famer joined forces with "The Bad Boy" Joey Janela to fight Brian Myers and Mojo's old WWE tag team partner, Matt Cardona in his first match back.

Aside from announcing his return to in-ring competition, Pac also revealed that he'd been wrestling with a torn ACL for about 14 years, but said he felt better thanks to surgery.

Now, the former D-Generation X member will again need to go under the knife.
