Quenneville declares van Riemsdyk will miss 'about a month'

After exiting Friday's contest following a hard collision with the goal post, Chicago Blackhawks defenseman Trevor van Riemsdyk will miss "about a month," head coach Joel Quenneville announced.

The 25-year-old was reportedly seen wearing a sling on his arm, and the Blackhawks are calling it an upper-body injury.

Van Riemsdyk has suited up in only two of Chicago's five games so far this season, yet to find the scoresheet.
