The Chicago Blackhawks have locked up another one of their defensemen to a new contract, as Riley Stillman has agreed to a three-year extension with the team.

Stillman, acquired by the Blackhawks in an April 8 trade that also brought Brett Connolly and the rights to Henrik Borgstrom to Chicago, will carry a salary cap hit of $1.35 million per season through the 2023-24 campaign, according to a press release from the team.
