Munich, Germany - updated After less than a year at the helm, Helmut de Raaf decided to step down as head coach of the Mannheim Adler Monday, following the team's 4-2 loss against expansion team Wolfsburg.

De Raaf assumed head coaching reins after the departure of Bill Stewart in January 2004. He will remain with the organisation, returning to his former job as a juniors coach.

Assistant Stephane Richer, a former Adler player and part of the Frankfurt Lions championship-winning coaching staff last year, was appointed new head coach. He will be assisted by former Adler goalie Mike Rosati.

Sunday action in the DEL

The Mannheim Adler held a 2-1 lead going into the final period against Grizzly Adams Wolfsburg Sunday. Wolfsburg rallied for a 4-2 (0-1, 1-1, 3-0) home win. Ivan Ciernik scored back-to-back goals, including the game-winner on a shorthanded breakaway at 9:23, and Petr Smrek added an empty-netter with only a second remaining.

ERC Ingolstadt suffered its third straight loss, squandering a 1-0 lead at home in a 3-1 (2-1, 0-0, 1-0) loss to the first-place Kölner Haie. The hosts went ahead on their first man-advantage when Martin Jiranek ripped a shot past Chris Rogles 4:20 into the contest. Cologne was quick to reply. The Haie tied the score at 1-1 when Lewandowski scored off a rebound four minutes later. The Haie, who went 2-for-5 on the power-play, then cashed in on their first man-advantage. Jean-Yves Roy scored the go-ahead goal, 2-1, re-directing a slapshot from defender Stephane Julien past Jimmy Waite with 3:47 left in the first. Ingolstadt kept pressing, but the defensive-minded Haie stood firm. Julien's power-play goal put the game out of reach at 3-1 2:25 into the final stanza.

The Hamburg Freezers squandered a 3-1 lead but rebounded with a last-gasp goal to edge the Krefeld Pinguine 4-3 (1-1, 2-2, 1-0) at home. Dave Tomlinson scored on the man advantage with only three seconds left in regulation to end Hamburg's two-game losing streak.

The Nürnberg Ice Tigers won in similar fashion, knocking off the Berlin Eisbären 3-2 (1-1, 1-1, 1-0) on a power-play goal from Tomas Martinec 10 ticks before the final horn.

Pat Lebeau provided a pair of third-period goals as the Frankfurt Lions erased a 1-0 deficit to skate to their fourth straight win, beating the hapless Kassel Huskies on the road, 3-1 (0-0, 0-1, 3-0). The Huskies drew first blood when Dany Bousquet scored midway through the second period. Christian Kohmann evened the score at 1-1, knocking a bad-angle shot from the left slot past Husky goaltender Joaquin Gage. Lebeau scored short-handed at 12:50 of the third to put the Lions in front, 2-1. It looked like a blown opportunity when Francois Bouchard missed the net wide right on an a breakaway with Lebeau, but Lebeau picked up the loose puck behind the net and scored on a wrap-around. He then added another goal with five minutes remaining to seal the deal, going topshelf on Gage's stickhand side on a 2-on-2 break with Dwayne Norris.

Shawn Carter led the way with three assists as the Augsburger Panther extended their win streak to three games with a 4-1 (2-0, 1-1, 1-0) home victory over the struggling DEG Metro Stars who suffered their fourth loss in a row. Klaus Kathan's tally on a 5-on-3 powerplay at 8:18 of the second went down as the game-winner.
