Now, Smith said he can walk and work out without any serious problems.
"I'm just enjoying where I'm at right now," Smith said.
Smith has acknowledged that he has likely played his last game and he is currently on the reserve/retired list. The Broncos put him there for salary-cap reasons in February, so he's not taking up a roster spot or using any cap room.
Still, he said he has to make sure about his decision before retiring officially.
"You can't slam the door on your opportunity when you still have a chance for it to be open," Smith said. "You can't just close the door on that. When it's time to close the door, trust me, I'm going to close it and wish the Broncos the best."
Smith gave advice to Broncos' receivers on the field after a recent offseason team camp practice. He has said the hours are too long to become a full-time coach, but he might find another role with the Broncos. He said he hasn't received any official offer from the team but would be interested.
"I love the Denver Broncos, I love the organization," Smith said. "So ain't nothing I wouldn't do to help, whether it's on the field or off the field."
