"He'll need more time," Rangers assistant general manager Thad Levine said. "He's making progress but we want to make sure he's not in harm's way."
Catcher Geovany Soto, who is also on the disabled list with a strained right groin muscle, is also eligible to be activated on Wednesday. But the Rangers will wait until Friday when they play in Houston. Soto is currently on medical rehab assignment at Triple-A Round Rock.
Soto is 5-for-12 with a home run in five games. The last step is for him to catch nine innings and then he'll be ready to be activated.
The Rangers are also expecting Chris Gimenez to return from paternity leave on Thursday. That's two catchers they have to activate and they don't have room for both unless they option either outfielder Daniel Robertson or Jim Adduci back to Triple-A.
"We have a few decisions on the horizon," Levine said.
