Since Derek Fisher is no longer in the NBA, is Matt Barnes taking the "out of sight, out of mind" approach when it comes to his former teammate? Maybe. Well, unless you bring him up! During Wednesday's game between the Memphis Grizzlies and Boston Celtics, a fan got Barnes' attention when Fisher's name was brought up, but he was quick to fire back, stating what allegedly happened in their now infamous altercation last October.

Celtics.com's Marc D'Amico has since deleted the tweet, but other Twitter accounts, like @MySportsLegion and @ebehoops have referenced the conversation and credited D'Amico.

Of course, this probably isn't the last time we will hear about the Barnes and Fisher fiasco. After all, the Grizzlies forward made it clear not too long ago that when he's retired, they "will cross paths again."
