"It was an easy decision to come back," Numminen told The Buffalo News on Wednesday from his home in Finland. "Being there two years, I really enjoyed myself and my family really felt comfortable in Buffalo. That was my first choice."
He reportedly received a one-year contract worth $2.6 million, the same as last season.
The 39-year-old Numminen had two goals, 27 assists and a plus-17 rating while missing only three games last season.
