Tyler Seguin tosses his mouthguard into a fan’s beer 3/25/13

Once thought to be Bruins assistant coach Geoff Ward, but now known to be Tyler Seguin (see the reflection in the glass to the left of Ward) casually tosses his mouthguard over the glass and directly into the beer of a fan behind the bench at the Bruins-Leafs game at TD Garden, on March 25, 2013.
