MIAMI — The arraignment for Cleveland Browns wide receiver Donte Stallworth on DUI-manslaughter charges has been postponed.

Prosecutors on Thursday asked a Miami judge to postpone the arraignment for 30 days while they complete their investigation.

Authorities say Stallworth was driving drunk when he struck and killed a pedestrian while returning from a night of partying in Miami Beach on March 14. The 28-year-old Stallworth was released by Miami authorities after posting $200,000 bail.

If convicted of DUI manslaughter, Stallworth faces a maximum of 15 years in prison.
