An already thin Boston Red Sox starting rotation will be without another arm with Walker Buehler going on the 15-day injured list.
Buehler, 30, was scheduled to start Friday against the Minnesota Twins but was placed on the IL after returning to Boston ahead of the team, which finished a series in Toronto on Thursday, to undergo tests on his right shoulder.
Red Sox manager Alex Cora said Buehler "hasn’t bounced back the way we wanted" since his start last Saturday versus the Cleveland Guardians. In that game, he gave up three runs, seven hits and one walk in six innings.
