Chicago Bears tight end Zach Miller announced his retirement on Tuesday, 18 months after he suffered a horrific knee injury.
He had hoped to return to the game but in an Instagram post said he just physically couldn't do it.
"The time has come to move on from playing the game of football," Miller, 34, said in the post. "It has been an incredible journey for myself and my entire family and we can't thank you enough for your continued support. I would love more than anything to step on Soldier Field one last time but I physically cannot give the game and our fans what they deserve."
On Oct. 29, 2017, Miller suffered a dislocated knee against the New Orleans Saints. He had emergency vascular surgery at a local hospital to repair a torn popliteal artery and ultimately save his left leg.
The injury eventually required nine surgeries.
The Bears re-signed him June 2018, knowing he couldn't play, to enable him to retain his medical insurance and rehab at the team's facility.
A sixth-round draft pick by Jacksonville in 2009, he played three years with the Jaguars and three-plus seasons with the Bears. He ends his career having played in 66 games (33 starts) with 146 catches for 1,631 yards and 15 touchdowns.
