Jansen has been dealing with flu-like symptoms since the All-Star Game, David Vassegh of AM 570 LA Sports reports.
The veteran reliever didn't have the greatest of weeks, as he spent the days following the All-Star Game battling a high fever and nausea. Although Jansen did appear in Friday night's contest - where he recorded his 22nd save in 22 tries this season - he said he felt dizzy while running to first base, so the Dodgers may elect to give him a couple days to get back to full health. Pedro Baez or Luis Avilan would likely fill in as the closer should that be the case.
