Chris Heisey (hamstring) is unsure when he'll resume a rehab assignment. Heisey is with the Reds on their road trip, but he hasn't been told when he'll start playing in rehab games again. "I haven't heard anything," Heisey said. "I feel good though." The outfielder was able to run at about 80 percent effort over a week ago, so he can't be too far off.
