Kenley Jansen could sit out the Los Angeles Dodgers' trip to Colorado this weekend due to ongoing problems with an irregular heartbeat.

Increased elevation can exacerbate an irregular heartbeat. Jansen previously had issues with his heart in 2012 and this year while playing the Rockies.

"With Kenley and altitude and going to Denver, it's certainly going to be a conversation we're going to revisit during this series," Dave Roberts said. "The No. 1 priority that we're all aligned on is that Kenley's health is first and foremost the priority. If there's any hesitation on his part or the doctors say the altitude can affect him in any way, then for us it's a no-brainer to have him stay back. So we haven't made a decision yet. We'll have those conversations and make that decision in the next couple of days."

Jansen spent 11 days on the disabled list this summer with a recurrence of his irregular heartbeat, which began to present itself while he was in Denver last month.
