"Sidelined Marlins ace Josh Johnson will see orthopedic surgeon James Andrews on Wednesday for an evaluation on his right shoulder.

The Marlins said Johnson, on the 60-day disabled list with inflammation, does not feel like his shoulder is 100 percent. For peace of mind he's visiting Andrews, who performed Tommy John surgery on Johnson in 2007, before continuing his rehabilitation program.

"We'll know more [Wednesday], but it's not great," President of Baseball Operations Larry Beinfest said. "He threw a pen on Friday and reported a little more stiffness and just didn't feel right. …It's obviously not what we were looking for in the progression."

Matt Sosnick, Johnson's San Francisco-based agent, termed the visit "strictly precautionary," and added that Johnson's shoulder seems to be fine. They just want to make sure.

Friday was Johnson's third side session. He can come off the disabled list as early as July 16, the third game after the All-Star break, but that might be in jeopardy now. Pitching coach Randy St. Claire said he was unsure how many rehab starts Johnson would need before rejoining the team.

"It goes on how he's feeling," St. Claire said. "If he's rolling, I feel that three would be fine. Even the sides he threw in Tampa…he's special. He hadn't thrown a side in a month and he goes out there and dots it like he hasn't missed a beat. It's like, 'Geez, can I use you tonight?'"

One scenario could have Johnson throw a simulated game, followed by two rehab outings to get his pitch count up around 70. St. Claire said he'd take back Johnson with an 85-pitch limit.

Since Johnson last pitched May 16, the rotation is 7-17 with a 4.99 ERA."
