After playing just four games and gaining just 74 yards in the 2010 season, Laurence Maroney had a very, very slim chance to remain an NFL player in 2011. Now it appears the running back has thrown that chance out the window. Maroney, 25, was arrested in St. Louis on weapons charges, according to KMOV-TV. There are no details just yet, other than that Maroney was in a car with three other men when the vehicle was pulled over by police.
