Pujols received his second dose of the COVID-19 vaccine and "just didn't feel good," manager Dave Roberts said. Roberts said Pujols will be reevaluated Wednesday.
Pujols, 41, is batting .255 with 12 homers and 38 RBIs in 82 games since he signed with the Dodgers on May 17 following his release from the Los Angeles Angels. The three-time National League MVP is fifth with 679 career homers, 17 shy of tying Alex Rodriguez for fourth.
Bellinger was hitting .159 in 89 games entering Tuesday's contest, with nine home runs and 34 RBIs. The 2019 NL MVP was not in the starting lineup against the San Diego Padres but entered late and went 0-for-1 in the Dodgers' 2-1 win.
