Jets cornerback Darrelle Revis has turned himself in to police in Pittsburgh following a weekend altercation that led to him being charged with four felonies and a misdemeanor.

Revis did not answer questions from assembled media as he made his way into the Pittsburgh Municipal Courts building at about 7:20 p.m. ET Friday. He was accompanied by attorney Blaine Jones and family members.

Police on Thursday charged Revis with two felony counts of aggravated assault, one felony count each of robbery and conspiracy, and a misdemeanor count of terroristic threats.

The incident at question occurred at 2:43 a.m. ET Sunday on Pittsburgh's popular South Side. Two men, ages 21 and 22, told police that Revis punched them amid a verbal altercation. Witnesses said the two men were unconscious for 10 minutes, according to police.

Dallas Cousins, a 22-year-old from Kittanning, Pennsylvania, was walking on a street when he spotted someone who resembled Revis, police said. Cousins confronted Revis, who acknowledged his identity. At that point, Cousins 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.

Zacheriah Jarvis, a 21-year-old from Ross Township, Pennsylvania, who is Cousins' roommate, helped retrieve the phone, police said. An argument ensued. An unidentified man came to help Revis. The other men told police they "were punched, then remember waking up to talk to police."

A witness, Nathan Watt, told police that Revis approached him after Cousins and Jarvis were knocked out. Watt quoted Revis as saying, "I got more guys coming." The complaint added that Revis "stepped within a foot of his face with an aggressive demeanor on his face, fists clenched, and stated, 'Do you want to be next?'"

Watt said he didn't know whether Revis or the man who helped him knock out Cousins and Jarvis, telling police, "I don't know. It happened so fast."

Officers viewed the cellphone video at the scene and confirmed the person in it was Revis. Police said the video "shows Revis walking away from the group and Cousins following him, describing what Revis is wearing. The video then shows Revis standing in front of the White Eagle Bar and stating, 'Why are you following me?' several times before the video stops."

The men said they later took themselves to the hospital and that Cousins was diagnosed with an orbital floor fracture.

Revis and the unidentified male fled the area in a truck, Watt told police.

Three calls were placed to 911, including one from Cousins. A cab driver and a resident also called 911, both saying they saw two men unconscious in the street.

On Thursday, Revis' attorney, Jones, said the four-time All-Pro was "physically assaulted while at the location by a group of at least five people" and was a "victim in all of this."

One of the NFL's most accomplished players, Revis is facing an uncertain future with the Jets. After a disappointing season -- he called it the worst of his career -- the 31-year-old 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).
