Former Jet defensive lineman Dennis Byrd was killed in a car accident Saturday morning in Oklahoma.  Byrd is best known for breaking his neck during an NFL game after running headfirst into a teammate.

Via ESPN: Byrd, 50, was pronounced dead at the scene due to massive injuries.

The highway patrol said the crash happened about 11:15 a.m. between Oologah and Claremore.

Byrd, who was driving a 2004 Hummer H2, was struck by a vehicle traveling northbound on Oklahoma Highway 88 and veered into his lane. The other car, a 2000 Ford Explorer, was driven by a 17-year-old Claremore youth.

Holy shit.  Talk about bad luck with headfirst and head on stuff.  Damn.  First breaking your neck running into a teammate headfirst and now a head on car crash.  Not a great way to go.  R.I.P. Dennis Byrd.
