Dodgers RP Jansen out until September
Jansen, who has been treated for an irregular heartbeat in the past, returned to the team hotel on Thursday night when he was feeling ill. He went to the hospital in Denver with the team's trainer before the decision was made to send Jansen back to Los Angeles.
"We're holding out hope it's not too serious," manager Dave Roberts said.
The Dodgers' four-game series with the Rockies runs through Sunday.
Jansen shares the National League lead with 32 saves entering Friday. The Dodgers used Scott Alexander to close Thursday's victory at Coors Field.
Roberts said altitude could be a factor.
"Anytime you're talking about the heart and irregular heartbeat, you've got to be very careful with it," Roberts said.
