yes on the blackhawks there's one. dustin bufflin
Pronounced the way you spelled it, but actually spelled "Dustin Byflugen". Go figure. He wears #33, which used to be worn by Dirk Graham when he was a star player and team captain for the Chicago Blackhawks.
Willie O'Ree played for the Boston Bruins in the 40s or 50s
Tony McKegney played for 15-20 years for a number of teams, including New York Rangers, St. Louis Blues, Detroit Red Wings, Buffalo Sabres. Back in the 80s and 90s when Wayne Gretsky and the Edmonton Oilers were whuppin' up on everybody and winning like 5 or 6 Stanley Cups, their goalie was Grant Fuhr, one of the best ever at that position. A goalie is to a hockey team what a quarterback is to a football team or a pitcher to a baseball team.

Mike Grier currently plays with Buffalo. Anson Carter used to play with Boston. He may be retired by now. There are probably a dozen or so black players in the league right now.
I used to be a goalie when I was growing up in Buffalo. then I got back into it again when I was in grad school. Haven't played in about 10 years now.
