After seeing that Henrik Sedin has not missed a game since before the NHL lockout, I decided to look up current iron man streaks in the NHL. He and Jay Bouwmeester are very close, both having missed their last game in 2003/04. Though it would appear that JB is the reigning NHL Ironman at over 500 games (if you only count regular season). Sedin has at least at 490 consecutive games (550 if you count playoffs), which is still well shy of the record set by Doug Jarvis at over 900. The Jarvis record is more impressive to me than the Cal Ripken record, given the amount of physical punishment that hockey players endure at high speeds. Martin St. Louis and Brad Boyes are north of 400 consecutive games and Travis Zajac rounds out the top five. Iginla has at least 328.
