HOUSTON – A video of JJ Watt's nephew standing up on his own for the very first time brought a smile to the Texans star's face following his season-ending injury.

Watt shared the video of his nephew via Facebook.

"‪That smile at the end can brighten up even the darkest day," Watt wrote.

‪Even on a tough day there is reason to smile.‬ ‪Texans win, the Stros are winning and my nephew stood on his own for the first time. ‬ ‪That smile at the end can brighten up even the darkest day. ‬
