Denver Broncos rookie cornerback Perrish Cox has been arrested for investigation of felony sexual assault.

Cox was taken into custody Thursday night following an investigation into an alleged Oct. 28 assault and brought to a Douglas County jail, said Michelle Kivela, public information officer for the city of Lone Tree, Colo., which is about 20 miles south of Denver.

Cox appeared yesterday in Douglas County Court in nearby Castle Rock wearing a gray prison uniform. His feet were shackled and he was escorted by an armed sheriff's deputy.

A judge declined a defense attorney's request to reduce a $50,000 bond but did say that Cox can leave the state two times - apparently to play in Broncos road games at Arizona this weekend and at Oakland on Dec. 19. Cox waived extradition, meaning he agreed not to fight transport back to Colorado if for some reason he were arrested out of state.

Cox posted bail yesterday afternoon and was released from custody, according to Douglas County jail guard Chad Walker.

The case filing was sealed at the request of the district attorney's office. Cox' next court hearing was set for Jan. 7.

The alleged assault occurred a few days after Cox was knocked out of a game against Oakland on Oct. 24 with a concussion. He spoke afterward about having no memory of the 59-14 rout and missed the team's trip to London for their Oct. 31 game against San Francisco.

Douglas County Court spokeswoman Casimir Spencer, prosecutor John Topolnicki and defense attorney Vince Buckmelter all declined to comment on the case.

When asked about the case, Cox's agent, Jordan Woy, said in an e-mail to the Associated Press, "We are still investigating the matter." He later added, "Perrish is meeting with the Broncos and we are dealing with this in a very serious manner."

The Broncos have not addressed whether Cox will play tomorrow. He was listed on the injury report as questionable with a non-injury, meaning there's a 50-50 chance he will be in uniform for the game.

"This is a serious matter and something we're taking extremely serious as an organization," Broncos interim coach Eric Studesville said. "We'll get all the facts together, get all the information we can, sit down and figure out what we're going to do based on the information we gather. It's disappointing news. Anytime you hear something like this, it always is."

* Police raided the home of Baltimore Ravens rookie kick returner David Reed earlier this week to investigate potential drug activity.

No charges have been filed, but police did take evidence from his residence, according to Baltimore County police spokesman Lt. Robert McCullough.

McCullough says police entered Reed's home around 10:30 on Tuesday night to "investigate potential narcotics activities." He said yesterday the evidence that was confiscated is being analyzed, and Reed "currently is not being charged with anything."

Ravens spokesman Kevin Byrne says the team is "aware of the situation" and has talked to Reed. Byrne said Reed will "have his due process and his opportunity to talk about the circumstances."

Reed has not been disciplined by the team and is expected to travel with the Ravens for Monday night's game against the Houston Texans.
