"No, it's not going to be tomorrow. I'm still limping a little bit when I walk, so I got to be pain-free first before I start running," Ortiz said before Tuesday's game against Detroit.
Ortiz took batting practice on the field at Fenway Park on Tuesday afternoon, but he won't be cleared to play until he can run without pain. He still feels discomfort in his right foot, which he injured July 16 while rounding the bases on an Adrian Gonzalez home run.
"Not like I used to, but there's still pain. That's why I'm still limping," Ortiz said.
The designated hitter will try to return to action by the weekend when the Red Sox host the Twins, his former team.
"Hopefully, we'll see once the pain goes away," said Ortiz, who leads the club with a .316 average, 23 home runs, .414 on-base percentage and .609 slugging percentage.
Tuesday marked the 14th game Ortiz has missed since the injury.
