The Boston Celtics played game three of the NBA Finals last night at TD Garden and it appears that a few Bruins were enjoying the festivities. This video was posted on Instagram by Brad Marchand's, wife Katrina (@kasloane), of Charlie McAvoy showing off his dance moves: <div align='center' class='pl20 pr20'><blockquote class='twitter-tweet' data-lang='en'><a href='https://twitter.com/bigbruinsenergy/status/1534731393749721088'> </a></blockquote></div> <b>Credit:</b> @bigbruinsenergy on Twitter. McAvoy is supporting quite the sling on his left arm from the offseason shoulder surgery he underwent recently. <i>Also tagged in the video was Marchand and rapper Nelly who was performing at the game. It looks like Craig Smith is the guy right behind McAvoy and former Bs defenseman Adam McQuaid is seen in the top left corner. </i>
