Johnson (undisclosed) remains unfit to play and will miss Wednesday's season-opener versus the Blues, Mike Chambers of The Denver Post reports.
Johnson missed virtually all of training camp with the undisclosed issue. The 32-year-old defenseman will likely need some additional time to get up to speed. Barring a remarkable turnaround, Johnson will miss Opening Night. While Johnson is out, look for Conor Timmins to see top-four playing time along the Avalanche's blue line.
