MIAMI — Browns wide receiver Donte Stallworth was charged yesterday with killing a pedestrian last month while driving drunk after a night out at a swanky South Beach nightspot.

An arrest warrant charging Stallworth, 28, with DUI manslaughter was filed in the March 14 accident that killed 59-year-old Mario Reyes. If convicted, Stallworth would face as many as 15 years in prison.

Stallworth’s blood-alcohol level after the crash was .126, well above Florida’s legal limit of .08, according to results of a blood test. Stallworth will also be charged with DUI, which carries a possible six-month sentence plus fines and community service for first offenders.

Stallworth, who is expected to surrender in court today, released a statement last month saying he was “grief-stricken” over the accident. Prosecutors said they will ask that he be released on $200,000 bail.

The Browns said in a statement that they are “disappointed” that Stallworth has put himself in this position.

“We are saddened by the circumstances that have taken place and our thoughts and prayers go out to the family of Mario Reyes,” the statement said. “We have been in communication with the commissioner, who is reviewing the situation under league policies, and we will withhold further comment at this time.”

Stallworth will be prohibited from driving while on bail and not allowed to drink alcohol, according to court documents. He also must observe a 12 a.m. to 6 a.m. curfew and must submit to random alcohol and drug testing through the NFL’s substance abuse program.

A Miami Beach police report said that Reyes was not in a crosswalk on busy MacArthur Causeway when he was struck by the black 2005 Bentley luxury car driven by Stallworth.

The report also quoted Stallworth as saying he flashed his lights at Reyes in an attempted warning and that Stallworth was driving about 50 mph in a 40 mph zone.
