"He'll get a chance with Edwar [Cabrera on Tuesday night] and Jeff Francis [Wednesday] and we'll also have a much better barometer as to exactly where he is at with that ankle," Rockies manager Jim Tracy said.
Rosario remains cautiously optimistic.
"I feel great, thanks to God," he said. "I've been working hard and looking forward to getting back out there. We'll see how I feel after the game."
Rosario injured the ankle trying to block a wild pitch against the Padres last Friday.
