MIAMI — Cleveland Browns receiver Donte Stallworth says he is "grief stricken" over his car accident that killed a pedestrian on a busy causeway linking Miami and Miami Beach.

Stallworth says in a statement released by the team Wednesday that his "thoughts and prayers are with" the family of Mario Reyes. Police say Stallworth was headed toward the beach when he hit the 59-year-old Reyes with his Bentley on Saturday morning. Reyes was near a crosswalk but it's unclear if he was crossing legally.

Stallworth said he could not comment further because the accident is under investigation. He was cooperating with police and no charges have been filed.

Police are awaiting a routine toxicology report expected late this week before releasing more details.
