Sidney Crosby will miss Thursday night's game against the Tampa Bay Lightning with an upper-body injury.
Pittsburgh Penguins head coach Mike Sullivan confirmed the news Thursday morning.
"Sid will not play tonight ... Right now his status is day to day, but my sense is it's going to be a week," Sullivan said.
Sullivan added the injury is not a concussion. Crosby missed practice Wednesday as the ailment was evaluated.
The superstar forward will miss his first regular-season game since the 2016-17 season.
