Nate Diaz scored a big win at UFC on Fox 3, submitting Jim Miller in the second round of the main event. Immediately after the bout, Diaz showed excellent sportsmanship. He pointed to Miller's shirt and said to the camera, "Buy those shirts! Support the cause!"

Diaz was referring to Miller's walkout shirt and his nephew. Miller's infant nephew Danny has polycystic kidney disease, and $10 of every walkout shirt sold will be donated to the Danny Miller Foundation to help him and other children with kidney disease. Several UFC fighters have donated memorabilia to auction off to get Danny closer to a kidney transplant, but the family still needs help.

Diaz knew that, and pushed his opponent's cause on national, network television. Diaz's last time on national television involved a post-fight melee that was an embarrassment to MMA. This time, he not only showed off his dominance as a fighter, but also his kindness as a man.
