The Chicago Blackhawks have signed rookie defenseman Jan Rutta to a one-year contract extension that will take him through the 2018-19 campaign, according to the team. The deal will be worth $2.25 million, per Elliotte Friedman of Sportsnet. Rutta has already appeared in 43 games this season, scoring six goals and handing out 13 assists while registering a net rating of minus-3 over 830 total minutes on the ice. The 27-year-old began playing professional hockey in the Czech Republic during the 2008-09 season, but he didn’t begin receiving significant playing time until 2011-12 when he skated in 48 contests for Pirati Chomutov, finding the back of the net twice while dishing out six assists. Rutta made his debut in Czech Extraliga, the country’s highest ice hockey league, the following year, participating in 37 games and firing one past the goaltender while assisting on three scores.
