Pittsburgh Penguins star Sidney Crosby is out indefinitely with concussion-like symptoms.
Crosby said Monday he noticed a recurrence of the problems that sidelined him for more than 10 months earlier this year following a 3-1 loss to Boston last week.
"Not (feeling) bad. I'm not happy about watching," Crosby said Monday after missing practice. "But I have to make sure with these sort of things that I'm careful and making sure I'm 100 percent before coming back. No timetable."
Crosby sat out Pittsburgh's two-game road trip to Philadelphia and New York as a precaution but said he's noticed familiar symptoms during light workouts over the weekend.
"I've been doing light exertion stuff and seeing how that goes," Crosby said. "It's that whole (recovery) routine again, but hopefully not as long. When I wasn't doing something for 6, 7 months that process was a little longer. Hopefully, that's not the case here."
The 24-year-old former MVP said there is no timetable for his return but he will definitely not play on Tuesday against Detroit. Crosby has 12 points in eight games this season, but hasn't scored a goal since netting two in his season debut on Nov. 23 against the Islanders.
