GREENBURGH - With lower-body injuries keeping both J.T. Miller and Sam Carrick from practicing Tuesday, the Rangers found themselves short a couple of centers at practice. So Mika Zibanejad stepped in for Miller as the first-line center, working with three wingers - Alexis Lafreniere, Gabe Perreault and Jonny Brodzinski - rotating around him. It was a chance, for a day, for Zibanejad to play the position he has owned for the Rangers for the past seven years.
