OTD: 48 years ago today, Bobby Orr played his final game for the Bruins; he recorded a goal and an assist in a 6-4 win. He could not play for the remainder of the season because of knee problems that required surgery, then signed with the Blackhawks in the offseason. #nhl #nhlbruins #hockey #bostonbruins #nhlplayoffs #bruins #nhlhockey #nhlmemes #boston #nhlallstar #nhldiscussion #nhlnews #nhledits #nhldraft #bruinsnation #nhlawards #nhltrade #hockeylife #tdgarden #nhlhighlights #bostonsports #bruinshockey #bruinsfan #nhlblackhawks #nhlglobalseries #nhlfi #nhlleafs #nhltrades #nhltradedeadline #nhlcanadiens
