John Madden has been noticeably absent from his nationwide (and KCBS, here locally) radio broadcast duties; for good reason; Madden underwent open-heart surgery last December, but the procedure went well and word was Madden would be back soon enough.
When he was still absent Super Bowl Week rumors began to swirl that he wasn't anywhere near recovery and that it would be some time, if any, before his return.
415 Media has learned, through a source, that Madden is OK but that scar tissue near his incision has been building. It's not known if he will return to radio.
Madden turns 80 next month.
