Acta said before Wednesday's game that Michael Brantley has been battling a sore right wrist for more than a week and will miss at least the next two games.
"He's been toughing it out and doesn't want to get out of the lineup, but our medical staff thinks that at least a day or two [off is needed] so it can heal properly," Acta said. "We appreciate him toughing it out, but we need to get him healthy."
Acta doesn't believe Brantley will miss too much time, though, and hopes to get his left fielder back in the lineup for Friday's series opener with the Rangers.
"He's been seen already in Cleveland," Acta said, "but he's going to have to take some time off. I'm planning just today and probably tomorrow. He's available, though."
