PITTSBURGH — Pittsburgh Penguins goaltender Marc-Andre Fleury skated alongside some of his teammates on Monday, but says he’s still dealing with concussion symptoms and is uncertain on when he will return.

Fleury hasn’t played since sustaining his second concussion of the season on March 31. He skipped Pittsburgh’s first-round win over the New York Rangers and appeared to experience a setback when he missed a pair of skates last week. Rookie Matt Murray filled in capably as the Penguins closed out the Rangers in five games.

Fleury said Monday the concussion is one of the toughest things he’s been through. The 29-year-old added he’s had good days and bad days when he wonders if “it’s ever going to get fixed.”

Pittsburgh opens the second round against the Washington Capitals later this week.
