Did you read the article? Guess not. No Poepping's not back.
Just to educate you, since you do not understand ACHA rules: (2009-2010 ACHA Manual Sec. II, Part B, Paragraph 8) "A Mens Division 2 student athlete participating in less than 20% of his teams games (including preseason & exhibition) shall not lose a year of ACHA Mens Division 2 eligibility in any one season."
Poepping did that and that's why he was able to play a "fifth" season.
