MILWAUKEE -- Jim Henderson's frustrating season came to a disappointing end Tuesday morning on an operating table in Florida.

The right-handed reliever underwent surgery on his right shoulder and will not return in 2014, manager Ron Roenicke said.

Henderson emerged as the Brewers' closer last season, racking up 28 saves in 32 opportunities but had problems with command and velocity during spring training and was replaced by veteran Francisco Rodriguez on Opening Day.

He got off to a slow start and had a 2-1 record and a 7.15 ERA in 14 appearances before landing on the disabled list with inflammation in his right shoulder on May 2.

Twice, Henderson went out on a minor league rehab assignment but the results weren't there and finally, the decision was made to operate on his shoulder for the second time in his career.

With an expected four-month recovery time, the 31-year-old's future is uncertain.

"It's a tough road," manager Ron Roenicke said. "Rehabbing is always tough. I'm sure he's got questions about whether he's going to come back or not. That's a tough thing to go through. Not a good year for it.

"Mentally, you get through it, and hopefully you heal up physically and are able to get back out there."
