MINNEAPOLIS -- Third baseman Trevor Plouffe visited hand specialist Dr. Thomas Varecka on Tuesday, and received good news about his bruised right thumb.

Plouffe, who is on the disabled list retroactive to July 21, was told there is no structural damage to his thumb, which was injured when he was jammed on an inside pitch against the Royals on July 20.

"It was a good report," general manager Terry Ryan said. "They didn't have to inject him. They didn't do a MRI. They just think it's a bone bruise. We'll move on as soon as he's ready, and we'll start the process here, batting practice and all that other stuff."

Ryan said he expects Plouffe to be ready to return once he's eligible on Aug. 5. Danny Valencia has been playing third base in his place.

Pavano delays first rehab start

MINNEAPOLIS -- Right-hander Carl Pavano was scheduled to make his first rehab start on Thursday in the Gulf Coast League but it was pushed back, according to general manager Terry Ryan.

Pavano, who has been on the disabled list since June 4 with a strained right shoulder, will instead throw another live bullpen session before deciding when to make his first rehab outing.

He was expected to throw about 40 pitches in his first rehab start but Pavano is being cautious, as he doesn't want to experience a setback.

"Pavano has pushed his official rehab back," Ryan said. "He's going to throw BP here this week. He's not quite ready to pitch in a game. We're going to move him back some. He's going to throw live BP on Friday. He doesn't feel strong enough to want to go and pitch in a game."

Wimmers to have MRI on right elbow

MINNEAPOLIS -- Alex Wimmers, No. 12 in MLB.com's ranking of Twins prospects, is headed to the Twin Cities this week to get an MRI on his right elbow after experiencing a setback last week.

Wimmers pitched two-thirds of an inning in the Gulf Coast League on July 23 in his attempt to come back from a strained elbow.

But it didn't go well, according to Twins general manager Terry Ryan. Ryan, though, wouldn't speculate that Wimmers needs Tommy John surgery just yet.

"I haven't gotten that type of information," Ryan said. "I'm not going to predict that. I don't know if that's accurate or not. Whoever you heard that from, it might be, I don't know. He wouldn't be coming up here if it was any good. It's something we think is serious enough for our people to see him here local, again. I don't know exactly the extent of this thing, but obviously, it's something we're concerned about, because we're going to fly him up here again. He's just not responding."
