Lucas 24:22

Moreover, certain women of our company amazed us, having been early at the tomb; and when they found not his body, they came, saying that they had also seen a vision of angels, who said that he was alive. And certain of them that were with us went to the tomb, and found it even so as the women had said; but him they saw not.

At the time these two disciples had left the circle of believers, the Lord had not appeared to any of them. Of course, the Lord had appeared early that day to Mary Magdalene; but it appears this was discounted by all of the disciples, as it certainly had been by the Eleven.
