An MRI exam Monday revealed that Milwaukee Brewers outfielder Ryan Braun is suffering from an oblique strain, and not an intercostal strain as originally believed, according to the Milwaukee Journal Sentinel.
There is still no timetable for his return.
"I think it's good to know exactly what we're dealing with, we can figure out exactly how to treat it," said Braun, according to the paper. "The primary purpose of the MRI was to figure out where the primary issue is so we can figure out what to do with it.
"I get treatment twice a day and hope for the best and see what happens. That's all you can do with these things. I'll get treatment as much as I can and do what we can to make it better."
Braun missed his second straight game Monday night. He was injured Saturday in a win over the Cubs.
"I asked the trainers what they think, but when you talk about the oblique muscle with Braun, it's really hard to guess at how long that takes," manager Ron Roenicke told the Sentinel.
"He was a lot better [Monday]," Roenicke continued. "I didn't think he'd be able to but with these things sometimes they come in and they're a lot better. If he's a lot better tomorrow, that means he can probably start taking BP and we'll see where we are."
Elian Herrera is starting for Braun in right field.
"It definitely makes a difference in the lineup," said Roenicke, according to the paper. "Right now, we don't have an option in what we're doing. Herrera is basically our guy. We have talked about putting [infielder Mark] Reynolds out there. Who knows? We may end up doing it or maybe we end up switching some personnel and try to cover."
Braun is hitting .318 with six homers and 18 RBIs in 22 games.
