Boston Red Sox reliever Carson Smith suffered a subluxation of his right shoulder when he threw his glove in the dugout Monday night, president of baseball operations Dave Dombrowski told reporters Tuesday.
Smith was placed on the 10-day disabled list Monday but Dombrowski said there was no timetable for his return.
Dombrowski called the injury “unfortunate” and said Smith is seeking a second opinion.
“It’s got the potential of being a major injury,” he said.
Smith allowed an eighth-inning home run by the Athletics’ Khris Davis in the Red Sox’s 6-5 loss Monday night. When he left the mound he threw his glove in frustration, causing the injury.
Smith is 1-1 with a 3.77 ERA and 18 strikeouts over 14.1 innings pitched.
Left-handed pitcher Bobby Poyner has been called up from Triple-A Pawtucket.
