Chapman, who began the season on the 15-day disabled list, has not resumed any baseball activity yet. He is scheduled to see a doctor for a check-up on Wednesday.
"I haven't done anything," said Chapman, who was hit by a Salvador Perez liner vs. the Royals in Surprise, Ariz. "Everything has been as instructed, resting at home and doing just normal things. I'm just waiting. The doctor is going to see me, and he will tell me when it will be OK to do other activities."
Chapman, who received a large ovation from fans during the pregame introductions, could return to the mound for the Reds sometime in late April or early May if he progresses as expected after his surgery to repair his fractures, with a metal plate being inserted into his head.
Since the incident, Chapman has sported a pair of black eyes and a puffy nose, but he reported having no side effects from his injuries. On Monday, he rode with teammate Mat Latos in a car for the annual Findlay Market Opening Day Parade.
"At the moment I got hit, I felt pain. That's the last time I felt pain," Chapman said. "I haven't had any symptoms, any vision problems, nothing."
