The three-time Pro Bowl selection, who was hurt in the Colts' preseason loss to Buffalo two weeks ago, will instead continue his rehab work amid hopes for a quick return.
"We are at the point where I'm letting it heal by itself. If anything were to happen, that can be an issue. But it's not what we are going to do. I'm not going to get surgery. Unless something else happens to it, I'm going to stay with the way it is now," he said Thursday.
The Colts open the new season against the Chicago Bears on Sunday night in the new Lucas Oil Stadium.
Saturday said he consulted with team trainers and doctors and obtained another medical opinion before deciding to wait for surgery. All the doctors agreed there was no need for an invasive procedure now, he said.
Saturday said he did not know when he would resume practicing.
Justice started the Colts' final preseason game against Cincinnati, and Richard has been working in practice with quarterback Peyton Manning. Saturday has been working with both players in position meetings and on the practice field.
