Sharper, 41, spent 14 years as an NFL player

Former NFL star Darren Sharper was sentenced to 20 years in state prison and ordered to register for life as a sex offender for drugging and raping two women, the Los Angeles County District Attorney’s Office announced in a statement obtained by PEOPLE.

Sharper, 41, pleaded no contest two years ago to two counts of rape by use of drugs. The disgraced football player also pleaded guilty to three counts of conspiracy to distribute drugs with the intent to commit rape.

On Oct. 30, 2013, Sharper met two women at a nightclub in West Hollywood and invited them to another party before taking them up to his hotel room, according to the release. He gave each woman a drink and both passed out. One of them woke up naked hours later with Sharper sexually assaulting her, and the second woman “interrupted his actions,” according to the release.

On Jan. 13, 2014, Sharper met two separate woman at the same club and again invited them to a party, said he had to stop at his hotel room, and invited both up to his room. He offered them both a drink and each passed out, and when they woke up hours later, one of the women believed she had been sexually assaulted.

Last year, Sharper pleaded guilty in Louisiana state court to two counts of forcible rape and one count of simple rape following incidents in August and September 2013.

Sharper is appealing the federal judge’s sentence, according to court records.

Sharper has been incarcerated since February 2014, when he was arrested in Los Angeles, where the first of his victims came forward. Additional victims later surfaced in Louisiana, Arizona, and Nevada.

In 2015, Sharper pleaded guilty to rape charges in Arizona, where he admitted to sexually assaulting one victim and trying to assault another. In Nevada, Sharper has pleaded guilty to one felony charge of attempted sexual assault.

Sharper spent 14 years as an NFL player and was a six-time All Pro player, doing stints with the Green Bay Packers, the Minnesota Vikings and New Orleans Saints before his retirement in 2011. He subsequently worked as an analyst with the NFL Network.

As an NFL analyst, Sharper was traveling to several cities for various games. His victims told authorities they had blacked out while drinking with him and woke up groggy to discover they had been sexually assaulted.
