Winterton was demoted to AHL Coachella Valley on Wednesday.
Winterton's demotion comes after the 21-year-old made his season debut versus the Avalanche on Tuesday, registering three hits, one blocked shot and a minus-3 rating in 9:28 of ice time. With the team not back in action until Friday's matchup with Vegas, Winterton was joined by Cale Fleury and John Hayden in heading down to the minors -- at least for the time being.
