It’s the first of two surgeries for Myers, who also needs surgery on his hip. That recovery time is estimated at 16-20 weeks.
Myers, who was acquired by the Jets in the Evander Kane trade last season, had nine goals and 18 assists in 73 games.
Winnipeg head coach Paul Maurice says that the plan was to have Myers undergo hip surgery at the end of the season, although the knee injury and subsequent surgery needed to be addressed first.
Maurice said that Myers needed his knee in order to recover from the hip surgery.
The Jets coach said that Myers' hip injury has been built up over several years and estimates that his defenceman will be back to full training between mid-August and September.
