From Eric Stephens of the Orange County Register:
This isn’t Noesen’s first serious injury. The 21-year-old forward also tore his ACL early last season, managing to play just two games for AHL Norfolk before missing the rest of the regular campaign (though he did return for four playoff games.)
Noesen was drafted 21st overall in 2011 by Ottawa. He was sent to the Ducks as part of the Bobby Ryan trade.
