SAN DIEGO -- Right fielder Jayson Werth was scheduled to play for Class A Potomac on Thursday, but he went to see his doctor in New York because he felt tightness in his right hamstring.
However, Werth is expected to get a rehab start for Potomac on Friday and stay with the team a few more days, which means he will not be activated from the disabled list on Saturday. Werth will likely re-join the Nationals sometime next week when they play the Giants in San Francisco.
"I want to see where he is at, when he can play some games," general manager Mike Rizzo said. "I think it's safe to say he is going to be pushed back a couple of days."
