Los Angeles Dodgers pitcher Kenley Jansen was taken to the hospital Thursday due to an irregular heartbeat, according to Andy McCullough of the Los Angeles Times.
Manager Dave Roberts said that the reliever will not be available for the rest of the series against the Colorado Rockies.
The 30-year-old has dealt with heart problems in the past, going to the hospital for an irregular heartbeat in both 2011 and 2012, the latter coming after a game at Coors Field in Colorado. He underwent heart surgery in October of 2012.
