Per Larry Brooks, winger Martin St. Louis is not ready to retire, but will not be returning to the New York Rangers. There is interest from the Devils and Penguins, apparently.
St. Louis was acquired from Tampa Bay at the trade deadline last year, along with a 2015 2nd round pick, for Ryan Callahan, 2014 and 2014 1st round picks, and a 2015 7th round pick. In his Rangers career, he put up 22-38-60 in 93 games. In the playoffs, St. Louis put up 9-13-22 in 44 games.
The Rangers made playoff runs to the Stanley Cup Final and Eastern Conference Final during his 1+ seasons in New York.
