Goldberg returned to Monday Night Raw for the first time in 12 years and accepted Brock Lesnar's challenge, announcing that he's coming back for one final match at the age of 49. Lesnar is arguably the most impressive athlete in pro wrestling, but Goldberg's in tremendous shape for a 49-year-old. He's also not even close to being the oldest to compete in a WWE ring.
Note: To make this list, we excluded stars who returned in a Royal Rumble. Here are the 15 oldest wresters to compete in WWE.
Goldberg: 49 years old (currently)
The Undertaker: 51 years old (WrestleMania 32, 2016)
Hulk Hogan: 53 years old (SummerSlam, 2006)
Vader: 55 years old (Raw, 2012)
Sting: 56 years old (Night of Champions, 2015)
Hacksaw Jim Duggan: 59 years old (Raw, 2013)
Ric Flair: 59 years old (WrestleMania XXIV)
Dusty Rhodes: 61 years old (Great American Bash, 2007)
Terry Funk: 62 years old (One Night Stand, 2006)
Jerry Lawler: 62 years old (Raw, 2012)
Sgt. Slaughter: 64 years old (Raw, 2012)
Vince McMahon: 67 years old (Raw, 2012)
Lou Thesz: 71 years old (untelevised Battle Royale, 1987)
We kept modern Royal Rumble participants off the list, but since Battle Royales operate under different rules and Thesz wasn't simply making a short appearance, he stays. Thesz also won the World Heavyweight Championship at the age of 50.
The Fabulous Moolah: 81 years old (SmackDown, 2004)
