The Blackhawks announced Monday that thay have agreed to terms with defenseman Slater Koekkoek on a one-year contract extension that carries a $925,000 cap hit. 

Koekkoek, 25, registered five points (one goal, four assists) in 22 games this past season since being acquired by the Blackhawks from Tampa Bay on Jan. 11 for a 2019 fifth-round pick and defenseman Jan Rutta, who re-upped with the Lightning on a one-year deal worth $1.3 million. The Blackhawks also sent Tampa Bay a 2019 seventh-round selection.

With the signing, the Blackhawks now have six NHL defensemen under contract for next season: Carl Dahlstrom, Erik Gustafsson, Koekkoek, Connor Murphy, Duncan Keith and Brent Seabrook. But that doesn't necessarily mean those six will be on the Opening Day roster in 2019-20. The Blackhawks are expected to be active this summer via free agency, and aren't likely to roll back the exact same blue line group. 

The Blackhawks started the offseason with 11 restricted free agents and have already crossed one of those names off the list in re-signing Koekkoek.
