Pittsburgh Penguins captain Sidney Crosby will not play Thursday against the Lightning with an upper-body injury, and he could miss more time.
"Sid will not play tonight," coach Mike Sullivan said. "Right now his status is day-to-day, but my sense is it's going to be a week."
Sullivan stressed that the injury is not a concussion, an issue that has plagued Crosby throughout his career.
It's not clear when Crosby was injured. He did not miss a shift and played more than 21 minutes during Pittsburgh's 4-2 loss to New Jersey on Tuesday night.
Crosby, 31, has 8 goals and 11 assists in 16 games, but the Penguins are struggling. Pittsburgh has dropped five of six games overall and is 7-6-3 nearly a quarter of the way into the season.
Pittsburgh shook up its lineup on Wednesday, trading forward Carl Hagelin to Los Angeles for Tanner Pearson.
