Washington Nationals Brad Lidge underwent hernia surgery Tuesday morning, his agent, Rex Gary, told The Washington Post.
Gary said the procedure went "very well," and the 35-year-old righty is expected to resume throwing in about three weeks.
He'll need a rehab assignment, but could return by the end of the month.
With Lidge out, hard-throwing Henry Rodriguez will likely serve as the team's primary closer.
Lidge signed a one-year, $1-million contract with the Nationals in late January. Reliever Ryan Perry was summoned from Triple-A to replace Lidge.
