St. Louis Rams defensive end Robert Quinn almost had a DWI arrest slide past unnoticed.

But Quinn wasn’t so lucky today when KSDK-TV in St. Louis reported that he was arrested for DWI nine days ago on July 10.

According to the report, Quinn was arrested in suburban Florissant at 5:40 a.m. and he was also charged with two other traffic violations. A police spokesman said Quinn was cooperative throughout the proess.

Quinn had five sacks last season as a rookie and the Rams are expecting bigger things from him this season under the new coaching staff.
