OAKLAND -- Right-hander Carl Pavano will be shut down for the rest of the season after an MRI exam showed a bruise on his right humerus bone, Twins assistant general manager Rob Antony said Tuesday.

Pavano, who was scheduled to make a rehab start with Class A Fort Myers on Tuesday, instead met with Dr. David Altchek in New York. Pavano, on the 60-day disabled list retroactive to June 2, with right rotator cuff weakness, was advised that only rest will cure his bone bruise, and he'll miss the rest of the season.

"I was a little surprised," Antony said of the diagnosis. "He was going to pitch today and then see the doc, but when they could get him in sooner he went and after Altchek looked at him, that's the thing. All along, I know our doctors and Dr. Altchek have conferred on everything. To me I'm not sure how many more medical opinions you could get, to have more tests done, or whatever, than we did."

Pavano has struggled with his velocity this season, as his fastball averaged just 86.8 mph after averaging 89 mph last year, according to Fangraphs.com. He last made a rehab start with Fort Myers on Thursday, but his velocity had not improved with his fastball, averaging about 85 mph.

Pavano, who is set to be a free agent after the season, finishes the year 2-5 with a 6.00 ERA in 11 starts. He made his last start on June 1 before originally being diagnosed by Twins doctors with a strain in his shoulder capsule.

"Injuries are a part of the game," Antony said. "Carl kept trying to pitch even when he was throwing 86 mph, he was trying to pitch through it. It got to the point where we had to shut it down and try and get him better, and then you turn it over to the other people."

Twins recall right-hander Hendriks from Triple-A

CWS@MIN: Hendriks fans five over 6 1/3 in Twins' loss

OAKLAND -- The Twins recalled Liam Hendriks from Triple-A Rochester on Tuesday, and the right-hander is scheduled to start Wednesday against the A's.

Hendriks will be starting in place of right-hander Nick Blackburn, who was outrighted to Rochester on Monday after struggling to a 7.39 ERA in 19 starts this season.

"I'm happy to be back up here, so hopefully we can move forward and stay up here," Hendriks said. "After I got sent back down, I told myself to just stop screwing around with my mechanics and get back to what I was doing in Spring Training. Step back, get set and throw. It was helping me out."

Hendriks was impressive in Rochester, posting a 2.20 ERA in 16 starts. He also struck out 82 and walked 28 in 106 1/3 innings. His last start came Friday, when he allowed four runs on seven hits over seven innings.

Hendriks, though, has had trouble translating his Minor League success to the Majors, as evidenced by his career 6.71 ERA in 12 big league starts. He's 0-5 with a 7.04 ERA in eight outings with the Twins this season.

"He's obviously had his struggles up here, but he's done very well in Triple-A," Twins manager Ron Gardenhire said. "Whether he can make the jump up here and separate remains to be seen. We'll get another opportunity to look at him. He's done what he's supposed to in Triple-A and they've actually told me he's the best pitcher in that league. And that's saying an awful lot. There's a lot of young arms in that league."

Span unable to get through MRI, still sits with injury

OAKLAND -- Twins center fielder Denard Span was scheduled to get an MRI exam on his right clavicle on Tuesday, but couldn't get through the exam because he was claustrophobic.

Span, who originally hurt his shoulder trying to make a diving catch on Aug. 12, said he was given medication to try to stay still for 35 minutes, but couldn't do it. He had a less-intrusive MRI exam taken on his neck on Monday, and that came back clean.

"I went and tried to get an MRI today and it didn't work out," said Span, who was held out of the lineup for an eighth straight game. "So today I didn't accomplish much. I felt better yesterday, so that was a good sign."

Span felt good enough to take batting practice on the field for the first time since the injury, and is expected to rehab without having the MRI on his right clavicle. He originally took X-rays on Aug. 12 that determined he didn't break anything.

So the Twins remain hopeful he'll stay off the disabled list, and cited their callup of fourth outfielder Matt Carson on Friday as a reason why they can wait.

"That's the reason we went to an extra player and dropped a pitcher, to see where this took us and to see how long it was going to be with Denard," Twins manager Ron Gardenhire said. "Our goal is not to put him on the DL, and we're still not right now. We'll see how it turns out; we'll see how it goes."
