The Dallas Stars appear set to add depth down the middle.

The club is expected to sign center Martin Hanzal when the free-agency window opens later Saturday, according to TSN's Bob McKenzie.

The Stars do have Tyler Seguin, Jason Spezza, and Radek Faksa down the middle, but, as Mike Heika of the Morning News adds, Spezza could be shifted to right wing to make room for Hanzal.

Hanzal, a capable two-way center, is coming off a five-year deal worth $15.5 million signed with Arizona in 2012. He was traded to Minnesota last season in hopes of boosting a long playoff run, and is averaging 0.52 points per game over the course of his career.
