Pittsburgh Penguins star Sidney Crosby tested positive for COVID-19, head coach Mike Sullivan announced Wednesday.

Defenseman Brian Dumoulin also tested positive. Sullivan added that Crosby is displaying mild symptoms and Dumoulin is currently asymptomatic.

Symptomatic players are typically expected to miss at least 10 days.

Defensemen Marcus Pettersson and Chad Ruhwedel were placed in the league's COVID-19 protocol Monday after testing positive. Kris Letang was present at practice Wednesday for the first time since testing positive on Oct. 23.

The Penguins have been dealing with COVID-19 cases since before the season even started.

Crosby missed the beginning of the campaign as he recovered from offseason wrist surgery and made his season debut Saturday.
