This is video of some youngsters from Royce Gracie Jiu-Jitsu as they took the mat during Saturdays "Grapple For A Cure" tournament.
This is the third year Royce Gracie Jiu-Jitsu has held the tournament, benefiting St. Jude's Children's Hospital.
"It's an amazing contrast, watching these very healthy, very talented kids, do all kinds of amazing Jiu-Jitsu moves, and in the end, it benefits a bunch of very sick kids," Tosh Cook said.
Organizers say the first two tournaments raised about $8,000.
They're hoping to raise another $6,000 this year.
