The man named Bear, of Man Vs. Wild fame, has been fired by the Discovery Channel.

Due to a continuing contractual dispute with Bear Grylls, Discovery has terminated all current productions with him, a Discovery spokesperson told The Hollywood Reporter, who first reported the firing.

The 37-year-old Grylls, who first appeared on the popular survival show in 2006, apparently refused to take part in two unnamed and unannounced projects that was part of his contract, sources told THR.

The seventh (and now final) season of Man Vs. Wild aired its finale (a behind-the-scenes episode) in November.

The entertaining, brave and always over-the-top outdoorsman, who has become the face of survival guide books, a Man Vs. Wild video game, an iPhone app and clothing line, has yet to issue a comment on the break-up with Discovery.

However, since Tuesday's announcement from Discovery, Grylls has been re-tweeting well wishes from his fans. Elsewhere in the Twitter world, fans have been expressing their frustration over the firing.

Bad move Discovery Channel, wrote Twitter user @Pyrao.

The Discovery channel fired Man Vs. Wild star Bear Grylls. Not sure what to do next, he will still drink tons & tons of his own urine, wrote @reinert03.

Grylls, is of course, also famous for drinking his own liquids in several episodes, including one involving snake skin.

According to THR, Man Vs. Wild averaged some 1.1 million viewers on the network with season five. Celebrities like Jake Gyllenhaal, Will Ferrell and Ben Stiller have all taken part in Grylls' adventures.

In his episode, appropriately named Men Vs. Wild, Gyllenhaal spends two days in chilly Iceland, doing everything from pulling himself across a 150 ft. deep river gorge via tightrope, making a snow cave, to slicing open a dead sheep.

This is one of those moments . . . face your fear. That is legitimately scary, Gyllenhaal says prior to the tightrope stunt.

With Man Vs. Wild out of the picture, Grylls still has a lot on his plate. The UK native will have plenty of publicity tours to look forward to (if he chooses to go on any). His memoir, Mud, Sweat and Tears, is scheduled to hit bookstores in May.
