"They haven't told me an exact date [I'll return]. They just have a progression they want me to go through every day. So far it's been going well."
Rays manager Kevin Cash said Guyer "looks really good," but they don't have a timetable set for the outfielder. He did say in the back of his mind he was leaning toward Guyer playing Tuesday.
"He probably could be ready to go, but we don't need him to re-aggravate anything."
Guyer said the pain is gone. He injured himself a week ago during batting practice.
"Felt it on a swing, then I took another swing, and I'm like, 'That doesn't feel right,'" Guyer said. "So I cut it short. Years ago when I did it to my right side, I tried to fight through it, and just made it worse. Just trying to be smart about it and not let it get to that point."
Guyer allowed that he's frustrated.
"Yeah, it's only been five or six days, but it feels like weeks," Guyer said. "So that's really frustrating. There's no good time to get hurt, but I guess now, during Spring Training, I'd rather do it now than during the season. At the same time, I want to get out there and get at-bats and knock the rust off. We'll see."
Looking at other injuries, Drew Smyly (left shoulder tendinitis) is still not throwing, though he is doing sock drills where he throws a baseball that's inside a sock.
Ronald Belisario (fractured left shoulder) said he is feeling well and added that he will have the shoulder X-rayed next week.
Alex Colome, who finally showed from the Dominican on Tuesday after having visa problems, stayed home Thursday due to a bug.
"He has stomach, fever, everything. Had a rough night last night," Cash said.
