PITTSBURGH -- Pittsburgh Penguins star Sidney Crosby will meet with a specialist this week because of lingering concussion-like symptoms.

Crosby hasn't played since Dec. 5 following a recurrence of the symptoms that sidelined him for more than 10 months last year. The team says Crosby will work with chiropractic neurologist Dr. Ted Carrick, who treated Crosby for similar symptoms last summer.

The 24-year-old star skated with his teammates for the first time in more than a month last Friday, a first step in what could be another long comeback. He continues to deal with dizziness and headaches and doctors have not cleared him to exert himself at a high level.

"The motion stuff is still a little bit iffy," Crosby said last Friday. "I want to make sure I give it a fair shot, but at the same time I know it's something I can improve."

Carrick worked closely with Crosby last summer after Crosby's progress slowed. Carrick said in September that Crosby would have a "very good outcome" following his rehab.

Crosby vowed to return this season, and he was spectacular in his season debut on Nov. 21, scoring two goals against the New York Islanders and had 12 points in eight games.

Yet all the good feeling faded after getting jostled around in a loss to Boston on Dec. 5.

There is no timetable for Crosby's return and though he called the chance to join his teammates on the ice a "positive step" it was also largely symbolic.

The 2009 NHL MVP is still uncertain when he'll be able to practice, let alone suit up for a game.

"Sidney has made a lot of progress but he is still having some symptoms, so this is the next step in his recovery," Penguins general manager Ray Shero said. "Obviously he won't be back in the lineup until he is symptom-free."
