MacKinnon missed Monday's practice session after taking a puck to the face Sunday, Adrian Dater of ColoradoHockeyNow.com reports.
MacKinnon's status hasn't been officially updated by the team but it seems unlikely the world-class center will be in action for Monday's preseason clash with Dallas. Unless MacKinnon misses regular-season contests, he should be capable of challenging for another 90-point campaign after having missed that mark by just two points last year.
