Drew Brees' offseason training included tackling a crocodile and eating it for dinner, scaling up and rappelling down narrow cave walls and jumping out of a helicopter.

The New Orleans Saints quarterback did all of that on the episode of NBC's "Running Wild with Bear Grylls" that aired Monday night. Brees and the survival expert spent two days in the Panamanian jungle for the show, which puts celebrities' survival skills to the test.

"The ironic thing is as a quarterback, they try to keep you out of harm's way when I'm on the field as much as possible," Brees said during the episode. "I don't know how I ended up having to basically wrestle a crocodile. … They might start putting that in contracts if they're gonna be watching this."

The episode began with Brees hitching a helicopter ride from a rooftop, then jumping into a river with Grylls in the jungle. When Grylls asked if he'd ever been to a jungle, Brees replied, "I've been to the Louisiana bayou a bunch of times."

"Well, this is just an accelerated version," Grylls said.

During their journey, the pair encountered bats, snakes and crocodiles -- one of which Grylls informed Brees would be their dinner. As Grylls secured its jaw with a noose, he had Brees pounce on it to pin it down, then stab it.

"I've done some hunting -- maybe not quite to this extreme. But there's a first time for everything," Brees said. "Of all the things you thought I might do today or asked me what I would do, the last thing I would have told you was stab a crocodile, gut it and then carry it out of the jungle. But that's what you do with Bear Grylls."

Brees was admittedly "terrified" before rappelling into the cave. While about halfway down, Brees yelled up to Grylls, "I'm doing good," then turned to the camera and muttered, "I'm not doing good."

Grylls found a creative use for a deflated football during that rappel -- slicing into it to let the air out, then placing it under the rope to let it glide more smoothly.

Brees also opened up about his life, his faith and his family several times during the episode. He got choked up while discussing his mother's suicide and shared stories about being teased about his birthmark as a child and dealing with his career-threatening shoulder injury in 2006.
