"I guess he's feeling better," Miami manager Mike Redmond said. "He said that he feels a lot better than he did [Friday], which is good. So whether or not he'll play [Sunday], I don't know that. We've got to make sure he's feeling good enough to go."
Morrison has played three games since the Marlins reinstated him from the 60-day disabled list on June 9. He is batting .444 (4-for-9) with six total bases, two runs scored and a .545 on-base percentage.
Morrison, who underwent offseason right knee surgery, had played five consecutive games through Tuesday -- two with Double-A Jacksonville and three with Miami.
Redmond said the team wants to ease Morrison and Giancarlo Stanton back into lineup in an effort to keep them healthy long-term. Stanton was in the Marlins' lineup for a fifth straight game on Saturday, but back issues have kept Morrison from doing the same.
"We'll make sure he's feeling good before he plays again," Redmond said.
