Since he hasn't played since the first two games of the season, Brian McGrattan is being dispatched to Milwaukee for a conditioning assignment, AKA "speed bag work". Seriously, I doubt he'll do much fighting there, as he has nothing to gain and much to lose should he get injured. The thing you really watch out for is a guy on the other team trying to make a name for himself by taking on a feared NHL heavyweight.
This came from the Preds:
Nashville Predators President of Hockey Operations/General Manager David Poile announced today that the club has assigned forward Brian McGrattan to Milwaukee (AHL) on a two-week conditioning assignment. McGrattan remains on Nashville's active roster during the conditioning stint.
McGrattan, 31 (9/2/81), has appeared in two games for the Predators in 2012-13. A season ago, he was claimed on waivers from Anaheim on Oct. 11, 2011 and played 30 games, notched two assists and recording 61 penalty minutes.
