Lopez will play three rehab games next week and might return to face the Red Sox next weekend, the Washington Post reports.
"I would like to think we'll get him back before the [All-Star] break," manager Lee Mazzilli said. "If not, I'm not going to push him." In daily leagues, leave Lopez out of your lineup until you see his name in a box score. In weekly leagues, only start Lopez for the following week if he comes back to play next weekend.
