Manager Dave Roberts said Wednesday that Glasnow (elbow) has yet to begin playing catch, Jack Harris of the Los Angeles Times reports.

The skipper added that Glasnow likely won't be activated once he's eligible to come off the injured list Aug. 31, but the team's concern is still relatively low. A clearer return timeline for the 30-year-old right-hander may emerge once he's able to begin a throwing program.
