Johnson was removed from Sunday's game against the Jets after he was checked into the end boards in the second period, Drew Spevak of ESPNDenver.com reports. Coach Patrick Roy didn't provide an update on Johnson's condition after the game, so his availability for the Avs' next game on Tuesday versus the Sharks will remain in question for the time being. Colorado is already down one defenseman with Ryan Wilson out two-to-three weeks with a shoulder injury, potentially putting the team's blue line in dire shape if Johnson, a top-pairing defenseman, is forced to miss time.
