ATLANTA -- Los Angeles Dodgers right-hander Daniel Hudson was placed on the injured list Saturday because of a season-ending torn left ACL.
The move was expected after Hudson's knee buckled in the eighth inning of Friday night's 4-1 win over the Atlanta Braves as he reacted to a dribbler hit by Ronald Acuna Jr.
Dodgers manager Dave Roberts said that "it was a clean tear of the ACL."
Hudson's recovery is expected to take six to nine months, taking away the team's top setup reliever. Hudson, 35, has five saves and a 2.22 ERA.
"Obviously, it's a big loss," Roberts said.
The Dodgers' bullpen previously lost another late-innings veteran, Blake Treinen, to a right shoulder injury. Right-hander Tommy Kahnle (forearm tightness) also is on the 60-day IL.
Brusdar Graterol or another pitcher must emerge as the next bridge to closer Craig Kimbrel.
"Obviously, the guys that are here are going to have an opportunity," Roberts said. "I'm not going to say who it is, but they're going to have opportunities."
The Dodgers activated infielder Hanser Alberto from the paternity list, recalled right-hander Mitch White and designated outfielder Stefen Romero for assignment.
White was called up to replace left-hander Andrew Heaney, who was placed on the 10-day injured list Friday because of left shoulder inflammation.
