Saunders had sat out the previous six games with a strained right groin and understands now he wasn't quite ready to return after the leg reacted while he was chasing down a line drive down the right-field line by Torii Hunter.
"I honestly don't think there's any setbacks at all," Saunders said prior to Saturday's game. "I thought I was ready and maybe I wasn't quite. It's tough to simulate game situations until you finally get out there and are running down fly balls off the bat.
"I really had to push it there, I felt it and it grabbed me and let me know it wasn't quite ready to be out there every day yet."
Manager Eric Wedge said the team will be cautious with Saunders, not wanting to risk losing him for the rest of the season.
"I think we'll give him a couple days and see how he feels," Wedge said. "He feels all right this morning, it's about where he's been. I'll talk to [trainer Rick Griffin] after he gets checked out and does a little bit of work and go from there.
"As I said last night, sometimes you just don't know until you get out there and it's game speed. He thought he was good, Rick thought he was good, he looked good to me. But obviously, I think we made the right decision getting him out of there."
