Ewing played three NFL seasons. He was with the Falcons from 2012-2013 and with the Jaguars in 2014. Jacksonville waived Ewing on March 31.
"After much thought and consideration, I have decited to retire from my NFL career," Ewing said in a statement. "This has been a very tough personal decision. Football has been an incredible forum for me to utilize my God given talents and has given me a lot of opportunity for growth through both success and adversity.
"Significant to me is that I feel like I am leaving the game in relatively good health considering the many injuries and surgeries I have sustained throughout my football career."
The Falcons took Ewing in the fifth round of the 2012 draft.
