The Columbus Blue Jackets fired general manager Jarmo Kekalainen on Thursday, ending his time on the job ahead of another crucial trade deadline for the struggling club. President of hockey operations John Davidson made the call midway through Kekalainen’s 11th full season on the job and with just over three weeks to go before the March 8 deadline. The 57-year-old Kekalainen, who is from Finland, was the third-longest tenured GM in the NHL.
