CHICAGO (AP) — The Chicago Blackhawks have agreed to an entry-level contract with defenseman Ian Mitchell, one of their top prospects.

The team announced the three-year deal on Monday. The start date and average annual value is up in the air because the NHL season is suspended due to the coronavirus pandemic.

Mitchell joins a promising group of young defensemen that includes 19-year-old Adam Boqvist, a first-round pick in the 2018 draft. Nicolas Beaudin, who doesn’t turn 21 until October, also could be a factor as soon as next season.

Mitchell, 21, was selected by the Blackhawks in the second round of the 2017 draft. He was a first-team All-American during his junior year at the University of Denver, collecting 10 goals and 22 assists during the regular season. He also served as team captain.

He finished his career with the Pioneers with 18 goals and 71 assists in 116 games.
