This isn’t The Onion. This actually happened.

NBA forward and notorious headcase Matt Barnes drove 95 miles from Grizzlies training camp to “beat the s**t” out of Knicks Coach Derek Fisher after discovering that Fisher is dating Barnes’ estranged wife, according to multiple reports. Fisher emerged from the fight with “a few scratches.”

Barnes’ wife, Gloria Govan, starred on the show Basketball Wives.

The NBA plans to probe the incident between Barnes and Fisher, who divorced his own wife after 10 years of marriage last spring.

Barnes was Fisher’s teammate for 3 years with the Lakers.
