Caleb Ferguson will have Tommy John surgery on his injured left elbow and is out for the season, Dodgers manager Dave Roberts announced before Thursday’s game against the Rockies.

Ferguson also had Tommy John surgery as a high school senior in 2014.

“Surgery is imminent, and I would expect it to be sometime next week,” Roberts said. “It's a long road ahead, but we're going to be with him every step of the way. He is a big part of what we're doing and what we are planning on doing going forward. I just feel terrible.”

Ferguson, who finished the season with a 2-1 record and a 2.89 ERA in 21 appearances, was injured in the bottom of the eighth inning in San Diego on Tuesday night. He grimaced after striking out Jurickson Profar and walked off the mound while motioning toward the dugout. He was placed on the injured list the next day.

Victor González is among the candidates to serve as Ferguson’s replacement.

Worth noting
• Joc Pederson, who was placed on the family medical emergency list Wednesday, is expected back early next week.

“We'll see,” Roberts said. “That could change, obviously. It’s family first, but the goal is to see him back on the field and in the lineup depending on who the pitcher is on Tuesday.”

Pederson, who has one hit in his last 11 at-bats, is slashing .174/.268/.376 with six home runs and 12 RBIs this season. He has two hits in 24 at-bats this month.

• A.J. Pollock, who left Wednesday’s game early with a hamstring cramp, was out of the starting lineup Thursday, but he is available off of the bench.

• The Dodgers will have a “bullpen day” against the Rockies on Friday. Roberts did not announce a starter, but he said the pitcher he chooses will not pitch the bulk of the game. Mitchell White, Keibert Ruiz and Scott Alexander are on the club’s taxi-squad.
