World Series champions the Los Angeles Dodgers placed Albert Pujols on the COVID-19-related injured list while activating Cody Bellinger, it was announced on Tuesday.

Pujols – a future Hall of Famer who will celebrate his 42nd birthday in January – had a reaction from his second COVID-19 vaccination shot.

The Dodgers have not placed a timeframe on Pujols' return but the two-time World Series champion and three-time National League (NL) MVP was ruled out of Tuesday's game against the San Diego Padres.

"He didn't feel good as far as playing in a major league game," Dodgers manager Dave Roberts said. "Just to give him a day and see where he's at tomorrow."

The Dodgers, though, activated 2019 NL MVP Bellinger from the IL after a left rib fracture sustained in an outfield collision with team-mate Gavin Lux on September 14.

Pujols is batting .255 with 12 home runs and 38 RBI in 82 games since arriving from MLB rivals the Los Angeles Angels in May while Bellinger – who also battled a shoulder injury earlier this season – is hitting .159 with nine homers and 34 RBI in 89 appearances.

The Dodgers (100-56) were second behind the San Francisco Giants (102-54) in the NL West division prior to Tuesday's games.

The Giants were dealt a blow with in-form Brandon Belt placed on their 10-day IL due to a left thumb fracture after being struck by a fastball against the Colorado Rockies on Sunday.

"It's not optimal, but I think we're going to be fine because our players are prepared for it," Giants manager Gabe Kapler said.

The Giants are yet to put a timeframe on Belt's injury but had said on Monday he will "continue to meet with doctors over the next couple of days to develop a recovery plan and timetable for his return."

Belt is batting .274 with a career-high 29 home runs, 59 RBI and 89 hits. The 33-year-old – a two-time World Series winner – leads the Giants for homers this season.
