Jets cornerback Darrelle Revis was charged with four felonies and a misdemeanor by Pittsburgh police on Thursday night stemming from his alleged involvement in a street altercation over the weekend that witnesses say left two men unconscious. Police charged Revis with two felony counts of aggravated assault, one felony count each of robbery and conspiracy, and a misdemeanor count of terroristic threats.
Revis' attorney, Blaine Jones, told ESPN that he was trying to reach the four-time All-Pro by phone Thursday night to arrange for him to surrender to police. Jones wouldn't say when Revis would turn himself in, but noted it would be "rather soon."
The incident occurred at 2:43 a.m. Sunday in Pittsburgh's popular South Side. Two men, ages 22 and 21, told police they were punched by Revis amid a verbal altercation. Witnesses said the two men were unconscious for 10 minutes, according to police. ...

The attorney said Revis was shoved by one of the men and attempted to walk away. The man who pushed Revis, he said, yelled at him. At that point, Revis knocked the cellphone out of the man's hand, according to Jones. "It's my understanding that when Darrelle turned around he wasn't sure whether it was a weapon or a phone," Jones told reporters. "He didn't know. ... "He feared for his safety." ...
Jones said Revis was "physically assaulted while at the location by a group of at least five people." According to police, a 22-year-old male from Kittanning, Pennsylvania, was walking on a street when he spotted someone who resembled Revis. The man confronted Revis, who acknowledged his identity. At that point, the man began recording video on his cellphone and continued to follow the NFL star.
"At some point, Revis snatched the cellphone away and attempted to delete the video," the police statement said. ...
According to the police statement, Revis tossed the cellphone on the street. A 21-year-old male from Ross Township, Pennsylvania, helped retrieve it. An argument ensued. An unidentified male came to help Revis. The other men told police they "were punched, then remember waking up to talk to police." ...
Revis, one of the NFL's most accomplished players, is facing an uncertain future with the Jets. After a disappointing season -- he called it the worst of his career -- the 31-year-old Revis could be a salary-cap casualty in the coming weeks; he's due a $2 million roster bonus on March 11, plus another $13 million in base salary (including $6 million guaranteed). Revis acknowledged he reported to training camp last season out of shape, contributing to his slow start. He has vowed to rebound in 2017, even saying he's willing to switch to safety. The Jets have been tight-lipped about Revis' status, even before last weekend's incident.
