A Facebook post on June 21 said Nelson "is not feeling well and, per doctor's orders, has been advised to rest for the next four days," adding that Nelson was "expected to make a quick recovery." Nelson's son Lukas Nelson and the country icon's touring band, Family, filled in for Nelson during his set. The ensemble played a "special set" including Nelson's classics.

Nelson is the headliner for the all-star New Jersey show, which includes Bob Dylan, Robert Plant and Alison Krauss, Mavis Staples and others.

The tour is scheduled to end Sept. 20 with a performance in New Hampshire.

The canceled tour appearances come after Nelson was inducted into the Rock & Roll Hall of Fame last year. The "On the Road Again" singer performed with Chris Stapleton, Dave Matthews and Sheryl Crow during the induction ceremony.

Nelson's latest album, "The Border," debuted in May.
