Survival expert-turned-Tv adventurer Bear Grylls has been dumped as the host of the Discovery Channel's hit show Man Vs. Wild.
The Brit's contract has been terminated by executives after he reportedly failed to honour his commitments to the network.
A source tells The Hollywood Reporter, "Due to a continuing contractual dispute with Bear Grylls, Discovery has terminated all current productions with him."
Reports suggest Grylls upset Tv bosses when he refused to participate in two mystery projects he was contracted for.
The adventurer's Man Vs. Wild series became an instant hit when it debuted on Discovery in 2006. Grylls also hosted the network's 2010 series Worst-Case Scenario.
Responding to the news, Grylls' representative Heather Krug, tells, "Bear's goal has always been to make life-empowering shows for his many fans around the globe, and he has taken great risks to bring Discovery such award winning programming over seven seasons.
"Unfortunately, Bear and Discovery have not been able to come to mutual agreement on new programming, and he disagrees with Discovery's decision to terminate current productions. Bear has loved the Man Vs. Wild journey and looks forward to producing further cutting edge content again soon for his loyal audience."
