(CNN) -- The Cleveland Browns wide receiver charged with killing a pedestrian last month while driving under the influence was expected to turn himself into authorities on Thursday morning.
The Cleveland Browns, in a statement, said they were "disappointed" in wide receiver Donte Stallworth.
Donte Stallworth was expected to surrender in court, according to the Miami-Dade County state attorney's office.
Authorities charged Stallworth, 28, with DUI manslaughter in the death of Mario Reyes, said the spokesman, Ed Griffith. The charge is a bondable offense, and bail is expected to be set at $200,000, he said.
According to Griffith, Stallworth's blood-alcohol level after last month's accident was 0.126 percent, higher than the state's legal limit of 0.08 percent.
Stallworth was at a Miami Beach club in the early morning hours of March 14 and was drinking, authorities allege in court documents. He later left the club and went to a Miami residence for about 45 minutes before leaving at 7:07 a.m. in his black Bentley GT, the documents said.
He was driving east on the MacArthur Causeway, which connects Miami to the South Beach area of Miami Beach, when he struck Reyes, a construction worker, prosecutors said. Reyes was crossing the eastbound lanes of the causeway.
CNN affiliate WSVN reported that Reyes, 59, was heading to a bus stop after leaving work.
"The victim was struck with the right front and fender of the vehicle," according to an affidavit filed in support of Stallworth's arrest warrant. "The force of the impact caused the victim to sustain critical head, chest and abdominal injuries." Reyes died a short time later at a hospital, the document said. Read the affidavit (PDF)
Stallworth told the arriving officer that he was the driver of the car and said, "I hit the man lying in the road," the affidavit said. After being advised of his rights, Stallworth told authorities that he had time to honk his horn and flash his headlights to alert Reyes, according to the documents. Police noted an odor of alcohol on his breath, the documents said, and Stallworth provided a blood sample at the scene at officers' request.
Stallworth released a statement four days after the incident, saying he and his family were "grief-stricken."
"My thoughts and prayers are with the Reyes family during this incredibly difficult time," he said.
The Cleveland Browns, in a statement issued on Wednesday, called the charges levied against Stallworth "very serious."
"We are disappointed he 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. 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."
Among the expected conditions of Stallworth's bail are that he consume no alcohol or drugs, submit to random drug and alcohol testing, abide by a curfew between midnight and 6 a.m., surrender his passport and not drive, according to an agreed-upon order setting conditions of his release. He will be allowed to reside in Ohio and Florida as needed, but must notify authorities 24 hours in advance when planning to travel between locations.
If convicted, he could face up to 15 years in prison.
Stallworth and his attorney have been cooperating with authorities, Officer Deborah Doty, spokeswoman for Miami Beach police, told reporters Wednesday.
Stallworth, a former University of Tennessee player, has also played professionally for the New England Patriots, the New Orleans Saints and the Philadelphia Eagles.
