Matt Barnes' beef with Derek Fisher shows no signs of letting up, as the Memphis Grizzlies baller spoke about his team facing off against Fisher's Knicks on Saturday (Jan. 16). Barnes made it clear that he was going to be civil at the upcoming game, but he made it seem like things will change after he retires. 

He told the New York Daily News, "I know I got to keep my mouth shut because then he'll run and tell. So we're focused on playing that team (the Knicks). And when I'm retired, him and I will cross paths again."

At the end of 2015, Barnes named Fisher in an Instagram post where he wrote, "Being stuck in the "triangle offense" w my ex & snitch, I mean former teammate & friend.. Who went behind my back, messed w my ex, got caught, got dealt w for being a snake, then ran & told the Police & NBA.. Instead of taken that ass whoopin like a man & kept it moving....!"
