Celebrity survivalist Bear Grylls tweeted yesterday: "Our man vs wild producer suffering from a brutal snake bite -- fighting the injury with courage, with the gut-wrenching photo.
Since then, the photo (which shows the skin rotting away from producer Steve Rankin's foot) has gone viral and is creating quite a stir in the social media world.
A Discovery Channel source told the Huffington Post that: "The photo was taken three weeks ago, when Grylls and Rankin were shooting a new series for the network called 'Naked & Afraid' Since then, Rankin has undergone surgery for the wound, and his prognosis is very good."
It's unclear where the team was filming and what species of venomous snake bit Rankin.
