Toronto Blue Jays pitcher Marcus Stroman will miss the entire season after tearing the anterior cruciate ligament in his left knee during fielding drills Tuesday.
General manager Alex Anthopoulos said the 23-year-old righthander will seek a second opinion from orthopedist James Andrews, and surgery is likely.
Anthopoulos said Stroman was participating in bunting practice when he was called off by third baseman Josh Donaldson. Stroman planted his feet to stop, then felt a pop in his knee. An MRI confirmed the tear.
Atlanta Braves lefthander Mike Minor will start the season on the disabled list because of inflammation in his pitching shoulder's rotator cuff.
Minor had an injection in his shoulder and won't throw for two weeks.
Gavin Floyd's comeback season could be over before it started.
The Indians said the righthander will be sidelined for "the foreseeable future" after reinjuring his troublesome pitching elbow. Floyd, who has made just 14 starts over the last two seasons, reinjured a stress fracture that limited him to just nine starts a year ago with Atlanta.
Floyd, who had Tommy John surgery in 2013, may need another operation. No timetable has been set for his return.
Toronto said Edwin Encarnacion likely will be sidelined for four to five days because of back inflammation.
