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.
