Stone didn't practice Tuesday due to the NHL's COVID-19 protocols.

EDGE Analysis

The Flames won't play their first game of the season until Saturday against the Oilers, so Stone could be cleared in time for that contest. Either way, the 31-year-old vet is currently one of the odd men out in terms of Calgary's blue-line corps, so he'll likely sit as a healthy scratch more often than not in 2021-22.
