Teenager Porter Ellett lost his right arm in an accident when he was small, but that hasn't stopped him becoming a high school basketball star.
Porter turns out for Wayne High School Badgers in the American state of Utah.
"It's kind of fun to see people's reactions when they doubt you and they see you walk out on the court and wonder what you are worth," he said.
Many of them end up being surprised, as Porter wows them with his steals, rebounds and slam dunks.

Porters's coach said: "He's got a winning attitude and he's a prime example of how far attitude can take you.
"It's not what happens to you, but how you react and how you deal with it that matters in life."
