The Boston Red Sox are holding All‑Star Willson Contreras out of Saturday night's lineup at the Los Angeles Dodgers as he undergoes concussion testing.

Contreras was hit by a pitch on the side of the helmet in the third inning of the Red Sox's 9‑4 victory over the Dodgers on Friday night. He left the game after being struck by a 95 mph fastball from reliever Will Klein.

The first baseman was checked by the medical staff before taking first base. He had already hit the dirt after Klein's first pitch of the at‑bat. Following Friday night's game, Red Sox interim manager Chad Tracy said preliminary tests on Contreras “have been fine.”

Contreras is hitting .288 with 23 home runs and 67 RBIs. The Red Sox are starting Nick Sogard at first base with Contreras out of the lineup.

The decision comes after the Red Sox won 9‑4, a game that showcased the team's offensive power and defensive resilience. Fans and analysts alike are watching closely as the team adjusts to the sudden lineup change.
