Sidney Crosby's injury doesn't appear to be serious.

The Pittsburgh Penguins superstar is day-to-day, head coach Mike Sullivan told reporters on Sunday. The bench boss added that Crosby was held out from practice for precautionary reasons and "his status is encouraging."

Crosby skated briefly before practice, but he didn't take part in the session.

The Penguins captain left Saturday's preseason game against the Buffalo Sabres and didn't return after blocking a shot in the first period. He was spotted leaving the arena with a slight limp, but without a walking boot or crutches, according to the Tribune-Review's Seth Rorabaugh.

Pittsburgh opens its 2019-20 regular season on Thursday at home against the Sabres.
