The 33-year-old spent last season in Washington and played all 48 regular season games. He scored 13 goals and 49 points in the lockout-shortened season.

Offense is the 6-foot center's game as he has scored at least 59 points in six of his last nine seasons. Ribeiro was on pace to exceed that mark again last season as he scored more than a point-per-game.
