Nicklas Grossmann is still suffering from post-concussion syndrome.

He is scheduled to revisit a neurologist in Pittsburgh on May 6, along with fellow Flyers defenseman Marc-Andre Bourdon, for follow-up exams. They are suffering from vestibular imbalance, which affects motion and balance. It is the same affliction that has hindered Chris Pronger from returning to normalcy.

According to Philadelphia GM Paul Holmgren, Nicklas Grossmann will probably miss the rest of the season because of a concussion issues.

"He has vestibular issues," Holmgren said, which means that Grossmann is having problems with his balance. Grossmann was injured on March 22 when he collided with a teammate at practice. He is great in leagues that count hits and blocks, but other than that he is a better player than fantasy asset.

Nicklas Grossmann's upper body injury is reportedly a concussion.

Grossmann hasn't played since March 18 as a result of the injury. Daniel Briere, when talking about his own recovery from a concussion, also suggested that Grossmann suffered a setback at one point. There's no timetable for Grossmann's return.
