Chris Narveson on 15-day DL

MILWAUKEE -- Milwaukee Brewers left-hander Chris Narveson is heading to the disabled list with a tear in his rotator cuff, an injury that is still being evaluated but may ultimately require surgery.

Narveson, the Brewers' No. 5 starter, is hopeful his injury won't need more than some rest to heal -- but he's also preparing for the possibility of surgery.

"You're always hopeful, but it all depends on what the doctor says," Narveson said Friday. "It's kind of in their hands. Sometimes, the outlook doesn't look too good, but we'll see."

The Brewers placed Narveson on the 15-day DL on Friday, retroactive to April 16. Right-hander Marco Estrada will start Saturday's game against Colorado in Narveson's place.

Narveson is seeking a second opinion and said he hasn't yet discussed the possibility of surgery with the team doctor.

"I think that may come up if that's the route that he thinks," Narveson said. "For now, we're just kind of trying to assess the situation."

The team described Narveson's injury as a tear, but Narveson said the nature and severity of the injury remained unclear as of Friday evening.

"They're not sure yet," Narveson said. "There's been some issues going on, obviously some red flags on the MRI. So I think there could be something that's going on in there, but I think we obviously wait until we get the opinions from everybody."

Brewers manager Ron Roenicke said Narveson has been sore since his most recent start, which came last Sunday in Atlanta.

"I know Chris was a little down when we told him we were going to DL him today," Roenicke said. "Hopefully, it's just a DL."

The Brewers were counting on a deep starting rotation to be one of their biggest strengths this season, and a long-term injury to Narveson would be a test for the team.

"We'll see how long it's going to be," Roenicke said. "If it's just a DL, it doesn't impact a team that much for 15 days -- it's basically two starts or three starts. So we'll see how long that's going to be. If it's long-term? Yeah, that makes a difference."

The Brewers also announced that right-handed reliever Kameron Loe will be placed on the bereavement list Saturday after the death of his grandfather.

The Brewers recalled right-hander Mike McClendon from Triple-A Nashville, and right-hander Wily Peralta is expected to be recalled from Nashville tomorrow to take Loe's roster spot.
