An icon may be hanging up his boots.

TMZ Sports is reporting that wrestling legend Sting is retiring.

The WCW, TNA and WWE star was injured while taking a bucklebomb from Seth Rollins last September at Night of Champions. Sting has not been seen on WWE programming since.

Sting said on the Dec. 9 edition of Ric Flair’s WOOOOO! Nation podcast that he and is “lucky that a catastrophe didn’t happen” in his match with Rollins.

According to TMZ Sports:

Sources connected to Sting tell us he was evaluated by several doctors who all agree — it’s just too risky for the wrestler to get back in the squared circle … so, he’s decided to hang up his singlet.

We’re told the 56-year-old was formally diagnosed with cervical spinal stenosis — a condition affecting the nerves that can result in extreme pain and discomfort.

In fact, it’s the same condition that forced fellow WWE superstar Edge to retire in 2011.

Our sources tell us Sting may make his official announcement next month at the WWE Hall of Fame ceremony in Texas … but we’re told it’s a done deal.

They also mention Sting is open to a non-physical role in WWE, but no offer has been made by the company.

He will the second active WWE wrestler to be inducted in the WWE Hall of Fame – the first being his inductor, Ric Flair. That, of course, if he doesn’t officially announce his retirement beforehand.

Glenn’s Take: It was great to see Sting wrestle in a WWE ring and battle for the biggest championship in professional wrestling. His Hall of Fame induction will be a tearjerker.
