"He's sore so just going to give him a day and see how he feels tomorrow," Brewers manager Craig Counsell said. "I mean, he got hit good. That's a bad spot to get hit. He needs that to swing the bat, so we'll see how he feels tomorrow."
Counsell added that he doesn't believe Gomez will miss much time and should return to the lineup soon.
Gomez has been a little banged up this year, also spending time on the 15-day disabled list with a strained right hamstring from April 17 to May 1.
"He's had a tough season, gets healthy some here, some there," Counsell said. "Unfortunately [he] hasn't been able to dodge just some random injuries."
Gomez was 3-for-7 in the series vs. the Reds with one home run and five RBIs. In Friday's opener, he hit his first career grand slam. Gomez is now hitting .269/.314/.423 with six home runs and 31 RBIs in 56 games this season.
Counsell also gave injury updates on pitcher Wily Peralta, who threw another successful bullpen session on Saturday, and left fielder Khris Davis.
"Everything was good and he'll throw to hitters [on] Tuesday," Counsell said of Peralta. "We're still looking at late July, but he is progressing now and we can start mapping things going forward."
Peralta has been on the disabled list since May 25 with a left oblique strain, and Davis has been on the DL since May 31 with a torn meniscus in his right knee.
"Khris will rejoin the team this week, early in the week," Counsell said. "Still on the homestand. ... It might not be tomorrow."
Davis had surgery on the knee in June and began a rehab assignment on Wednesday with the Class A Wisconsin Timber Rattlers.
