On the 15-day disabled list since July 27, Schafer said he's felt pretty good swinging the bat, but is still experiencing some swelling.
"As long as I can swing, I want to try and play," Schafer said. "I'm just anxious to get out there and start playing. It is no fun sitting around and watching everyone else play. It is not what I would prefer to do."
However, the 24-year-old is resigned to the fact that he'll have issues with the injury for the rest of the year.
Manager Brad Mills has been told by team doctors that the finger might not be 100 percent until Spring Training.
"When he can't hurt the finger anymore, then I'm comfortable with that," Mills said. "But until we get the doctors to sign off on that, we're in the situation we are at right now."
The plan is for Schafer to take batting practice again on Monday and Wednesday and begin a rehab assignment later on Wednesday if there are no setbacks.
Schafer has yet to take the field for Houston since being acquired in the trade which sent Michael Bourn to the Braves.
"I don't want to come over here and not play for two months, so hopefully I can get out there soon," Schafer said.
