The Sharks have officially re-signed restricted free agent Chris Tierney to a one-year contract. Tierney collected 23 points (11g, 12a) in 80 games in his third season with the Sharks last year, serving primarily as the team’s fourth line center after Tomas Hertl returned from a knee injury in January. “We believe Chris has yet to hit his prime, but has already proven that he can be a key member on our penalty kill and the defensive side of the puck,” Sharks general manager Doug Wilson said in a media release. “We are excited to watch his offensive development as he continues to use his strong two-way hockey sense to impact the youthful infusion of our roster.” The contract was first reported by TVA Sports’ Renaud Lavoie on Monday. The deal is reportedly worth $735,000.
