NFL star Za'Darius Smith retires from league at 33

Smith, a three-time Pro Bowl pass rusher, who was in his 11th year in the league, announced his decision in a post on social media.

"I knew this day would come - but now that it's here, I'm feeling so many emotions I never expected," he wrote on Instagram. "Who would've thought that a kid from Greenville, AL, with just one year of high school football experience, would go on to play professional football in the NFL for 11 incredible years!

"This game has given me the opportunity to meet great coaches, compete alongside some of the best players ever, and represent some of the greatest organizations in the league. Football has transformed my life and my family's lives forever - and for that, I'm forever grateful.

"This career has taken me across the world - from earning my first passport stamp to visit countries I only saw on maps, to helping me start a foundation that gives back to my community. There have been challenges along the way, but the rewards have outweighed them all and helped me learn, grow, and evolve as a man."

Smith then spent time with the Minnesota Vikings, Cleveland Browns and Detroit Lions before he joined the Eagles this season.

He will retire with 70.5 sacks and 343 tackles in 145 career games.
