Misa, 18, and Dickinson, 19, each found out they had cracked the Sharks' season-opening 23-man roster on Monday and went through their first practices as NHL players on Tuesday. Still, there is no guarantee they'll play against the Vegas Golden Knights in Thursday's season-opener, which begins a three-game homestand. Dickinson was on the fourth defense pair Tuesday with Vincent Desharnais, and Misa was left out of the Sharks' initial line rushes.
