"I've gotten better each and every day, and the training staff's been working out all those muscle issues, and I've felt a lot better this morning and am excited," Norris said. "[Manager Brad Mills] wanted to give me a couple of more days and go on Friday, and I have no problem with that. I'll be ready to go Friday and be 100 percent."
Norris experienced tightness in the arm last week after sleeping awkwardly on it. He was held to three innings in his most recent start, on Friday against the Nationals, but retired nine of the 10 batters he faced.
Right-hander Lucas Harrell will pitch Wednesday's game against the Marlins instead.
"I could have gone [on Wednesday] if necessary, but Skip just wanted to give me a couple of extra days," Norris said. "I'll be ready when my time comes and the lights come on."
