"Weighing all the different options, we felt like this was the right way to go," manager Joe Maddon said.
Scott has been on the disabled list since July 21 with a mild strain of his right external oblique.
"I just talked to him on the phone," Maddon said. "What we did is, we planned him out for the next three days. He's going to stay [with Class A Charlotte]. He's going to play some defense, DH and first base just to get him back on the field.
"Right now there are not enough at-bats for him [with the big league club]. ... We'd like him to sharpen his bat up a little bit, [have him] play a little defense -- get stretched out in case we need him there, too. Just based on what's coming up right now, we thought it was the right way to go about it."
Scott had a good day on Tuesday, hitting an opposite-field home run in the Stone Crabs' game in Bradenton, Fla., and Maddon said "he's doing well."
Though the chances of Scott joining the team on this road trip are slim, Maddon did not totally rule out the possibility.
"We're going to re-evaluate him on Saturday," he said. "It's probably going to be that way, but if something comes up, you could see him sooner."
Maddon said that Scott was disappointed with the news.
"Absolutely he was," he said. "I said, 'I understand your disappointment. I appreciate it.' But I also told him I appreciate [his] professionalism. How he handled the moment. How he spoke. That's exactly how it came out."
Scott is hitting .225 with 12 home runs and 45 RBIs in his first season with the Rays.
