Red Sox star J.D. Martinez was placed on the team's COVID-19-related injury list Saturday, the Sox have announced.
The designated hitter and outfielder was replaced on the roster by infielder Michael Chavis, according to Red Sox Chief Baseball Officer Chaim Bloom.
The announcement came just before the Red Sox' game against the Baltimore Orioles. The team didn't give any details about whether Martinez had tested positive or how long he was expected to be out.
Martinez is a three-time all-star, including in 2018 and 2019 with the Red Sox. He's hit .433, including two home runs and 12 RBIs mainly as a designated hitter, in the first seven games of the season.
The Sox were 4-3 entering Saturday's game in Baltimore.
Chavis played 42 games with the Red Sox last year and 95 the year before. He has a .241 batting average in the MLB.
