Buffalo Bills defensive tackle Ed Oliver joined the growing list of NFL players with recent off-the-field issues on Saturday night as he was arrested in Houston on charges of DWI and unlawful carrying of a weapon. Oliver, 22, was taken into Montgomery County Jail after police were reportedly tipped off by another driver that someone in a Ford pick-up truck was not maintaining their lane. Multiple reports state Oliver had an open beer can between his legs when he was pulled over and a pistol was later found in his car.
