Cossa allowed one goal on 12 shots in Sunday's 4-1 preseason loss in Colorado.
Cossa played the first 40 minutes of Sunday's game before being replaced by Michael Hrabal in the final stanza. Utah gave up a first-round pick to get Cossa on the night of the 2026 NHL Draft, so he will likely be given every opportunity to earn the backup role behind Karel Vejmelka this season.
