According to the report, Holland injured the knee during a fall at his home Tuesday morning and had surgery Friday to repair cartilage damage and clean out the knee.
“I am devastated by this injury,” Holland said in a statement provided by the club. “It was a freak accident at home that resulted in a hard fall on my knee. As upsetting as this is, my goal is to begin rehab and get back on the mound as quickly as possible.”
Holland went 10-9 last season with 1.29 WHIP, pitching 213 innings and setting career-bests for strikeouts and ERA.
