UPDATE 4/1/2019 5:05 PM ET: Rolling Stone has confirmed Mick Jagger will be undergoing heart valve replacement surgery. A timetable on when The Rolling Stones will return to touring is still unknown.

The Rolling Stones made headlines over the weekend after they had to postpone their upcoming “No Filter” North American tour due to Mick Jagger needing undisclosed “medical treatment.” Whatever treatment he need must not be incredibly serious, however, because Jagger was spotted on the beach in Miami just yesterday (March 31.)
