Meanwhile, a doctor has determined that outfielder Juan Gonzalez does not have a hernia, but Gonzalez will nonetheless have his activity scaled back in the coming days.
Ryan, sidelined for two days with a strained right intercostal muscle, will meet with Dr. George Paletta on Saturday to determine an exact course of action. At that time, Ryan also hopes that any other possible causes of the discomfort in his side will be ruled out.
"Basically, it's just finding out for sure and then aggressively treating it so we can get back as soon as possible," Ryan said.
Johnson, meanwhile, met with Paletta on Thursday but will confer with the medical staff again on Saturday. He has not appeared in a Grapefruit League game as he attempts to recover from tendinitis and a rotator cuff strain in his left shoulder.
He has been ruled out for Opening Day, and a timetable for Johnson's return to pitching has yet to be established.
"He feels better, progressing, but there is no change in his plan at this point," said general manager John Mozeliak. "We'll revisit it probably on Saturday. At that point they can consider some alternatives, whether it's a change in meds or if you'd do an injection. But at that point they'll make that determination."
Gonzalez has an abdominal strain and has not appeared in a game since March 10. He had been taking swings in batting practice and even in simulated and Minor League games, but it is expected that he will cease even that level of activity. Still, there was some relief that the injury is not a hernia.
"They're going to change how they approach it, and then re-evaluate it in probably five to seven days," Mozeliak said. "They're probably going to look at how they're treating it right now, and back it off a little bit where they see if that can quiet it down."
