Jonathan Niese said he plans to undergo a procedure to permanetly correct the irregular heartbeat condition he's dealt with the last two seasons.

Similar to Kenley Jansen, Niese will undergo surgery during the offseason. The Mets have yet to give an exact date, but the recovery timetable is only three days, so it's not considered a major issue. Niese will report to spring training at 100 percent.
