Christian Yelich will miss the remainder of the season after fracturing his right kneecap on Tuesday night.
The Milwaukee Brewers announced the extent of the injury following their 4-3 victory over the Miami Marlins.
David Stearns said Yelich will return to Milwaukee for additional tests on Wednesday, adding that it's not yet known if he'll need surgery.
The 27-year-old was injured in the top of the first inning when he fouled a pitch off his kneecap.
"First and foremost, we feel awful for Christian. This is a guy who's carried us in a number of ways over the last two years," Stearns said. "He could've [been] two-and-a-half weeks away from a repeat Most Valuable Player award. So that's where our thoughts go first.
"From a team perspective, we've got a lot of guys in that clubhouse who will hurt tonight. This is a gut punch for a night. And then we need to recover and play really strong baseball. We've been through this before as an organization -- two years ago, almost to the day, we lost Jimmy Nelson to a similarly freak injury, and we competed at a very high level for the remainder of that season. And I expect our team to compete at a similarly high level going forward."
