Greaves was called up by Columbus on Wednesday.
Greaves has made one appearances with AHL Cleveland this year and had a difficult time, posting a 7.01 GAA and an .800 save percentage. He has a 3.44 GAA and a .912 save percentage across 10 career NHL regular-season games. His promotion to Columbus might indicate that the availability of Elvis Merzlikins or Daniil Tarasov is in question for Thursday's home contest against Buffalo, but at the moment, neither of the Blue Jackets' regular two goaltenders have a reported injury or illness. If either Merzlikins or Tarasov can't play Thursday, then Greaves will probably dress as the backup netminder.
