MIAMI BEACH, Fla. (AP) — Police are awaiting a toxicology report before releasing details about their investigation of Cleveland Browns wide receiver Donte Stallworth, who hit and killed a pedestrian with his Bentley over the weekend.

Police spokesman Juan Sanchez said Monday that the routine blood work had not made it to the lab for testing yet. Sanchez said results are expected by the end of the week.

Authorities said Stallworth was headed toward the beach Saturday morning when he hit 59-year-old Mario Reyes on a busy causeway linking Miami and Miami Beach.

Stallworth was cooperating with police and no charges have been filed. A message seeking comment was left on the voicemail of his agent, Drew Rosenhaus.

The Browns said in a statement they were aware of what happened but would not comment until the investigation is complete.

A videotape obtained by The Miami Herald shows Stallworth being given a sobriety test just feet from paramedics trying to revive Reyes.

Stallworth signed a seven-year, $35 million contract with the Browns as a free agent before last season but hardly played because he was hurt. He was scheduled to receive a $4.75 million signing bonus Friday.
