2006-07: Bjorn Krupp, the son of former NHL defenseman Uwe Krupp, skated for the TPH Thunder midget team in Huntsville, Alabama and was selected by the Belleville Bulls in the second round (36th overall) of the 2007 OHL Priority Selection.
2007-08: Krupp spent the season with the US National Team Development Program. In 43 games he had 3 assists with 40 PMs. In six games at the World U17 Hockey Challenge he was scoreless with 4 PMs.
2008-09: Krupp played in 57 games for the Belleville Bulls (OHL), scoring one goal and adding three assists. He registered 22 penalty minutes and was a +9 for the season. In 17 playoff games for the Bulls, he did not register a point.
2009-10: Krupp played for the Minnesota Wild's Traverse City prospect team and was signed to a three-year, entry-level contract in September 2009. He returned to Belleville for his second OHL season; skating in 67 games for the Bulls. He had 11 assists with 53 PMs and was a discouraging -42 on a Belleville team that had the OHL's second-worst record.
2010-11: Krupp returned to Belleville for a third OHL season with only marginally better results. He skated in 61 of 68 games, scoring 1 goal with 10 assists, and was -35 with 54 PMs. The Bulls slipped into the playoffs despite winning just 21 games but held high-flying Mississauga St. Michael's to 11 goals in four playoff games (unfortunately Bellville scored once). Krupp was -3 with 2 PMs for the series.
2011-12: Krupp joined Kolner Haie in Germany's DEL after three seasons in the OHL. Skating in 48 of 52 games, he was third on the team with 70 penalty minutes and was minus-five with 8 assists. Kolner Haie, coached by Bjorn's father and former NHL defensemen Uwe Krupp, finished ninth in the league and advanced to the playoff quarterfinals. Bjorn Krupp was minus-two with no points and 2 penalty minutes in four playoff games.
2012-13: Krupp played 40 games for regular season champion Kloner Haie in his second season in Germany's DEL. He scored 1 goal with 8 assists and was +5 with 22 penalty minutes. Kolner Haie reached the playoff finals; falling to fourth-place Eisbaren Berlin. Krupp skated in all 12 playoff games and was -1 with 2 assists and 8 penalty minutes. He also played eight games for EV Duisburg in the German Third Division: scoring 1 goal with 4 assists and 2 penalty minutes.
Krupp certainly has the size to eventually become an NHL defenseman. He is responsible in his own end of the ice, but lacks skill. He'll be a defensive defenseman.
Krupp is now playing for the Cologne Sharks in Germany. Bottom-pairing defender.
