The Brewers optioned Henderson to Triple-A Nashville on Sunday.
Henderson will head back to Triple-A one day after the Brewers called him up to serve as their 27th man in a doubleheader with the Royals. The right-hander started the second game of the twin bill, taking a no-decision in the Brewers' 8-2 loss while striking out three batters and allowing two earned runs on three hits and one walk.
