New York Mets broadcaster Ron Darling is expected to take a leave of absence because of health concerns.
Per USA Today's Bob Nightengale, two friends of Darling said the former All-Star will announce his leave on Saturday.
Per SNY.tv (h/t Yahoo Sports' Matt Ehalt), Darling will have a medical procedure done next week after tests revealed a mass on his chest, but he could be back on the Mets' broadcast in May if there are no complications.
