Greg Jennings has announced his retirement from the NFL after 10 seasons.
Jennings said he was "done" with football and is "excited to be done."
"The past 20 years of my life has been football, but today that all changes," he says in the video.
"This smile is not going to be removed -- it's going to be enhanced. The same dedication, the same work ethic that I put into pursuing that sport, this game, I'll be pursuing everything else with the same mindset," he said.
Jennings, 32, said, "physically I know I can do it, I can still play ... but I feel like as though I would be going back to football instead of moving forward."
Jennings signed with the Dolphins last season following his release by the Vikings. Jennings played his first seven seasons with the Pacers.
