Bear Grylls, rugged adventurer and star of the Discovery Channel's popular "Man vs. Wild" series, has been injured during an expedition in Antarctica, the network said.

A fall resulted in a shoulder injury to Grylls, who is en route back home to Britain for medical treatment and assessment of the injury's severity, according to Discovery.

He was not filming for Discovery, but instead was taking part in an independent expedition.

The 34-year-old Grylls has hosted "Man vs. Wild," on which he strands himself in remote locations to demonstrate survival techniques, since November 2006.

The former British Special Forces member recently published "Man vs. Wild: Survival Techniques for the Most Dangerous Places on Earth."
