The Blackhawks and Kevin Hayes officially have parted ways, making one of the top young prospects in hockey an unrestricted free agent.

Hayes was the Hawks’ first-round pick (24th overall) in the 2010 draft and after spending four seasons with Boston College needed to reach a contract agreement before midnight Friday. Instead, the sides could not find a way to make things work and Hayes is free to sign with any team in the NHL.

“We offered Kevin what we believed was a generous and fair contract,” Hawks general manager Stan Bowman said in a statement. “Unfortunately, he felt it was in his best interests to become a free agent. We are looking forward to the compensatory draft pick we are receiving.”

As compensation for not signing Hayes, the Hawks will receive a second-round pick (54th overall) in the 2015 draft.
