In the early morning hours of Dec. 8, Dallas Cowboys nose tackle Josh Brent crashed his Mercedes, killing his passenger and former college teammate Jerry Brown. Brown was a practice squad linebacker with the Cowboys and, as Brent has described him, &quot;my very best friend.&quot; Brent failed a roadside sobriety test and was charged with intoxication manslaughter and released on bail. Brent was spotted days later attending Brown's memorial service and on the Cowboys sideline during a game. Brent left during the third quarter after learning his presence, at the request of his teammates and Brown's mother, was causing controversy. He has since been banned from games.
