Fan Appears to Tell LeBron James to 'Suck It Up' During Game vs. Thunder

It's a cold world for LeBron James.

During Sunday's heavyweight bout with the Oklahoma City Thunder, a fan appeared to tell the Cleveland Cavaliers superstar to "suck it up" while he was—surprise!—arguing a call.

Cavs head coach Tyronn Lue seemed to hear the comment and briefly turned toward the fan next to him.

Last time this happened, James death-stared the heckler. This time he seemed too focused on protesting.

After his Cavs beat OKC 115-92, LBJ made light of the incident by posting it on his Instagram account:
