NeuFit physical fitness company recently posted some rare photos of the Undertaker from their Instagram account, revealing that the Dead Man has been rehabilitating chronic knee pain with electrical stimulation therapy for the past few months.

According to them, while the former World Champion doesn’t normally allow photos while rehabbing, he was so thrilled with the result that he "happily" posed for this pic:

"Regarded as one of the greatest professional wrestlers of all time, Mark Calaway, better known by the ring name, The Undertaker @undertaker, is an American professional wrestler. ⚡️💀⚡️Our general manager, Rich @rich_dougherty has been working with him for several months, once a week, to help him get out of pain, especially around the knees. Let us just say that this man DOES NOT usually allow pics of any kind but he is so thrilled with his results that he happily posed for us. And YES, this is his happy face, y’all! Also, Rich might have had to endure a choke slam to get this pic, but he did it! 💀💪⚡️😂 Reminder: NeuFit is not just for the pros"


The Undertaker last appeared on SmackDown 1000 episode where he cut a short promo. He along with Kane are currently scheduled to face DX at the Crown Jewel event next month.
