The Braves are missing shortstop Yunel Escobar, who is day to day with a strained left adductor.
Houston manager Brad Mills says Berkman tweaked his left groin running to first base in his last at-bat against Cincinnati on Thursday night. Geoff Blum is the fill-in starter at first base.
Berkman missed the first 12 games of the season following arthroscopic surgery on his left knee on March 13.
Omar Infante is filling in for Escobar, who suffered his injury Thursday at St. Louis.
Also, Braves manager Bobby Cox plans to push back right-hander Jair Jurrjens' next start to May 8. Jurrjens suffered a strained left hamstring in Thursday's start.
