Cleveland Browns wide receiver Donte' Stallworth today pleaded not guilty to DUI manslaughter charges stemming from an accident in Miami in which a pedestrian was killed by a car driven by Stallworth.

Police say the NFL player was drunk when he struck 59-year-old Mario Reyes on a Miami Beach causeway. He faces up to 15 years if convicted.

Currently, Stallworth is free on $200,000 bail and did not attend this morning's legal proceedings.
