It's not a show I watch, but Green Bay Packers WR Greg Jennings plays a role on the USA Network show, Royal Pains. The episode premieres tonight. From ESPN:
"I got a chance to see how an entire show was put together," said Jennings, who appeared on CBS' "Criminal Minds" last year. "It was a totally different experience for me. It was something I always wanted to do."
He'll be playing himself, so obviously it won't be too hard for him to get into character. I'm interested to see how much screen time he gets.
