Building on a report from early September, Dodgers closer Kenley Jansen is slated to undergo a heart procedure on November 26. The estimated recovery time ranges from two to eight weeks, according to comments Jansen made Friday, and he expects to be able to rejoin the team once spring training rolls around next year. Jansen, 31, was first diagnosed with an irregular heartbeat in 2011 and missed significant time during the 2011, 2012, and 2018 seasons due to the condition.
