Milwaukee Brewers manager Ron Roenicke spent Tuesday morning at a Chicago-area hospital with back pain.
Roenicke told WTMJ radio that he couldn't sleep at night, so he phoned team doctors on Tuesday.
"My back's been bothering me a little bit," he told the radio station. "Everything's fine. It's just the back. Once in a while, my back gets a little squirrely."
He said he plans to be on the bench for Tuesday's game against the Cubs.
