Dodgers first baseman Adrian Gonzalez left Friday night's game against the Cubs with a right knee contusion, suffered during a slide at home plate in the first inning.
The team says Gonzalez is day-to-day.
Gonzalez was on first base in the opening frame when Hanley Ramirez grounded a ball to shortstop, but Starlin Castro 's throw to second base sailed into right field. Dee Gordon scored on the play to give the Dodgers a 1-0 lead, and Gonzalez never stopped running, trying to score from first base.
Gonzalez technically beat the relay throw home, but in sliding his foot never touched the base and he was tagged out.
The play was upheld on official review by the umpires.
Gonzalez remained in the game for one more inning before getting replaced at first base by Scott Van Slyke in the top of the third.
Gonzalez has been one of the most durable players in baseball for nearly a decade, averaging 159 games per year from 2006-2013. In 2014, he leads the Dodgers with 106 games, 104 starts and 909 defensive innings this season. Gonzalez is second on the team with 450 plate appearances, three behind leadoff man Dee Gordon.
