(AP Photo/Kathy Willens)Pittsburgh Penguins star Sidney Crosby will miss Tuesday night’s game against Philadelphia after being placed on the COVID-19 protocol list. The Penguins did not hold a morning skate ahead of the game, in line with the league’s COVID-19 guidelines. The news comes a day after the NHL had a season-low four players in the COVID-19 protocol. Crosby leads the Penguins with 18 points and is tied for the team lead with seven goals. Tuesday night’s game will be the first game with fans in attendance at PPG Paints Arena since last March.
