Greaves was reassigned to AHL Cleveland on Monday.
Greaves' demotion ahead of Tuesday's clash with Toronto would seem to indicate that Elvis Merzlikins (upper body) will at least be healthy enough to serve as the backup against the Leafs. With youngster Daniil Tarasov having secured the No. 2 role in Columbus, it will take another injury or a trade of Merzlikins for Greaves to get another opportunity this season.
