Wolski, 26, signed a one-year, $600,000 deal after he scored 12 points in 31 games last season between the New York Rangers and Florida Panthers. He was sidelined most of the season with a groin muscle injury.
He had signed a two-year, $7.6 million deal with the Phoenix Coyotes in 2010 after he recorded a career-best 65 points. He dropped to 35 points the following season and was dealt to the Rangers in midseason.
