"We are taking all of the necessary precautions to ensure Mr. Cosby's safety and general welfare in our institution", Corrections Secretary John Wetzel told the network. They evaluate the inmate's needs and programs, along with his health issues, she said.
Five other accusers took the stand at the trial as part of an effort by prosecutors to portray Cosby - once known as America's Dad for his role on the top-rated "Cosby Show" in the 1980s - as a serial predator.
Cosby's publicist said afterward that a forensic expert found that a tape Constand's mother made of a 2005 telephone call with Cosby had been manipulated in two places and was "not an authentic recording".
Bill Cosby's appeal of his conviction for sexual assault is expected to focus on a Pennsylvania judge's decision to allow several accusers to testify against him, but his challenge faces significant hurdles, according to legal experts.
The sentencing comes after Constand's victim statement was released earlier today, where she wrote that "Bill Cosby took my handsome, healthy young spirit and crushed it".
When he got to prison, Cosby was "in good spirits last night", said Lisa Durand, spokesperson for SCI Phoenix, according to CNN.
Really dude? Really? You're comparing serial rapist Bill Cosby to Jesus H. Christ?
The former comedian, 81, has been accused by dozens of women of drugging and raping them, with allegations of sexual abuse spanning decades.
During the sentencing hearing, which began on Monday in the US, Judge O'Neill heard from both the defense and the prosecution, as well as testimony and victim impact statements from the women, who have accused Cosby.
The AP does not typically identify people who say they are victims of sexual assault unless they come forward publicly, which Constand and other accusers have done.
However, she had one of his attorneys read a lengthy statement outside court following the sentencing, claiming prosecutors used "falsified evidence", citing what she described as a doctored recorded phone call between Cosby and Constand's mother.
"No one is above the law". ( I hope they get their day as well) So y'all are going to sit here and tell me that all of these women are lying? FOH! The women say that Cosby and his agents deemed them liars by denying their sex assault accusations. His wife, Camille Cosby, was not present.
