NEW YORK -- Boston Red Sox general manager Ben Cherington offered an encouraging prognosis on rookie left-hander Brian Johnson, who earlier this week was placed on the seven-day disabled list in Triple-A Pawtucket with inflammation in his left elbow.
While offering no timetable on when Johnson will resume throwing, Cherington said tests indicate there is no structural damage to the elbow, and that it should respond to conservative [rest and rehabilitation] treatment.
"He was feeling something in his forearm," Cherington said. "There was some inflammation in and around the joint. We're confident it can be treated conservatively, and optimistic he'll be throwing again in not too long. No timetable.
"We did the diagnostics, and no evidence there's anything going on with the ligement or anything other than conservative treatment."
Johnson felt soreness in the elbow in the fourth inning of his last start, Sunday in Buffalo.
"I don't really know too much to be honest," he told Tim Britton of the Providence Journal Thursday in Pawtucket. "Right now they just want me to rest and go from there."
Cherington also said that Mookie Betts, who has not played since he tumbled over the bullpen wall in Fenway Park July 28 and went on the seven-day concussion DL the next day, went to see Dr. Micky Collins in Pittsburgh for a consultation.
Collins is the clinical and executive director of the University of Pittsburgh Sports Medicine Concussion Program. He has treated former Red Sox players David Ross, Stephen Drew and Brock Holt for their concussive symptoms.
"As far as I know the reports are good," Cherington said. "Hopefully, he'll rejoin the team in Detroit and be much closer to baseball activity."
