The charge carries a possible 15-year prison sentence. Stallworth's blood-alcohol level after the crash was .12, well above Florida's legal limit of .08, according to results of a blood test. Stallworth will also be charged with DUI, according to the people informed about the case.
Stallworth, who is expected to surrender in court Thursday, released a statement last month saying he was "grief-stricken" over the accident.
A Miami Beach police report said that Reyes was not in a crosswalk on busy MacArthur Causeway when he was struck by the Bentley luxury car driven by Stallworth. The construction crane operator was trying to catch a bus home after finishing his shift around 7:15 a.m.
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.
Stallworth signed a seven-year, $35 million contract with the Browns before last season but was injured much of the year. He previously played for New England, Philadelphia and New Orleans.
