Green Bay Packers running back DuJuan Harris said Wednesday that doctors discovered a "fist-sized cyst" on his lung near his heart.
Harris did not practice with the team Wednesday, but confirmed via Twitter that the medical issue would sideline him for the short term.
"Should be 110% very soon and back to work. Thanks for the prayers and keeping me lifted!!!," Harris wrote.
The Packers drafted two running backs -- Eddie Lacy and Johnathan Franklin -- in April, leaving Harris, Alex Green and James Starks to battle for the remaining roster spot or two.
