Per Mark Berman of Fox 26 in Houston, Correa suffered a hand contusion and will be listed as day-to-day.
Correa was hit by an errant pitch from Frankie Montas in the top of the ninth inning of Houston's come-from-behind 10-6 victory. Pitcher Mike Fiers filled in as a pinch runner for the Astros shortstop.
Any significant absence from the young star could be devastating for the club.
The 22-year-old phenom has been a major run-producer in the middle of the lineup for Houston since entering the league during the 2015 season. Although Jose Altuve has been the team's best hitter, Correa is not far behind as one of the best young shortstops in the game.
After the 2012 No. 1 overall draft pick tallied 22 home runs in just 99 games during his first season to win the American League Rookie of the Year award, he followed that with 20 home runs and a .274 batting average during his second year.
His 96 RBI were also the most in the majors among shortstops.
Third baseman Alex Bregman is capable of sliding over to shortstop, as is Marwin Gonzalez, but the team will need everyone on the roster to play well in Correa's absence.
