Mike Tyson is sporting a neck brace and a significant scar after undergoing  surgery to fix a degenerated disc.

The boxer, 46, showed up to a charity auction held by the World Boxing  Council and Hublot Watches in Las Vegas with the large scar on his neck.

It has since emerged that Tyson recently went under the knife and had  titanium pins inserted to support his neck as a result of an old spinal injury  which had been causing him pain.

Tyson tweeted an explanation on Sunday, writing: “I was damaged before I even  entered boxing.”  Ain't that the truth! We pray for his recovery!
