Milwaukee Brewers star Christian Yelich left Tuesday's game against the Miami Marlins with an apparent injury to his knee.
Per Fox Sports Wisconsin's Sophia Minnaert, Yelich was replaced by Trent Grisham in the first inning when he fouled a ball off his knee.
An extended injury could be the worst-case scenario for Milwaukee, especially with the team fighting for a playoff spot.
Yelich is once again in the National League MVP race with a .330/.430/.672 slash line, 44 homers and 97 RBI in 129 games.
The Brewers entered Tuesday's game with a 75-68 record, two games behind the Chicago Cubs for the second wild-card spot in the NL.
