Miami Marlins outfielder Griffin Conine was placed on the injured list Sunday and is expected to miss at least two months with a dislocated shoulder.

Also on Sunday, Marlins left-hander Patrick Monteverde was designated for assignment, while left-hander Cade Gibson and infielder Ronny Simon were added to the major league roster.

Conine, 27, was injured on a dive into second base Saturday against the Philadelphia Phillies. Miami immediately placed him on the 60-day injured list, with an MRI scheduled for Monday to determine the extent of the injury.

Conine was batting .281 with one home run and seven RBIs in 20 games this season. Over 50 career games in two seasons, he is a .274 hitter with four home runs and 19 RBIs.

Monteverde, 27, made his major league debut Saturday and gave up four runs on nine hits over 3 2/3 innings.

Gibson, 27, and Simon, 25, each had their contracts purchased from Triple-A Jacksonville and are being called up to the major leagues for the first time.

Gibson was 1-1 with a 4.50 ERA in four relief appearances at Jacksonville, while Simon was batting .354 with one home run and nine RBIs in 15 games.
