"I guess we'll see how it goes after playing catch," Henderson said. "I've been doing strengthening exercises all week long, and it's been getting stronger. Pain-free with all of the movements we've been doing. That's all positive."
Sunday's session will be light throwing from 60 feet. Henderson will have to slowly build back to the mound, and he will probably go on a Minor League rehabilitation assignment before returning to action. That process could take several more weeks.
