The Los Angeles Dodgers received approval Tuesday to replace injured pitcher Michael Grove with fellow right-hander Ben Casparius on their National League Division Series roster.

The nature of Grove’s injury was not yet revealed. He faced two batters in the Dodgers’ Game 2 loss to the San Diego Padres on Sunday, allowing a solo home run to Xander Bogaerts before striking out Jake Cronenworth to end the eighth inning.

By rule, Grove will be ineligible for the Dodgers’ NL Championship Series roster should they advance. He would be eligible to return for the World Series.

Grove, 27, is in his third season in the majors and pitched 39 games in the regular season, starting two. He went 4-4 with a 5.12 ERA. In 64 major league games (20 starts), Grove is 7-7 with a 5.48 ERA, with 151 strikeouts in 149 1/3 innings.

Casparius, 25, is a rookie who made his major league debut in August. He threw 8 1/3 innings over three relief appearances in the regular season, tossing 12 strikeouts and going 2-0 with a 2.16 ERA.

The Dodgers continue their series, tied 1-1, Tuesday night at the Padres.
