Chavis (elbow) will be shut down from gripping and throwing activities for the next 5-to-7 days, Kevin Gorman of TribLive.com reports.
The 26-year-old was placed on the injured list with the right elbow injury Tuesday, and he'll be shut down from most activities for about a week. Chavis should have enough time to rejoin the Pirates before the end of the season, but he likely won't be activated until the second half of September.
