Federal drug enforcement agents are investigating at least two MDs who prescribed drugs to Heath Ledger.

Immediately following the actor’s death, DEA reportedly subpoenaed several documents from the NYPD and the Medical Examiner to try to determine exactly where Ledger got his cocktail of prescriptions that eventually caused his death. The agents are looking into whether these drugs were properly prescribed by physicians.

The drama series which made headlines about its transition from internet to TV, “Quarterlife,” succeeded in being a flop in its NBC debut Tuesday night, having the worst ratings in at least 20 years, according to Nielsen Media Research.

The show designed to address audience between 18 and 49 didn’t succeed to rise to the expectations of NBC.

According to a source at NBC, the series might be canceled before the next episode.

An NBC spokeswoman said that the series will remain in the schedule and that it was moved to Sundays.

“Quarterlife” was created for the internet by producers of “My So-Called Life” and “thirtysomething,” Marshall Herskovitz and Edward Zwick. It’s been around for three months with episodes of seven to nine minutes being transmitted on its own website and My-Space TV.

The broadcast from Tuesday only draw an average of 3.1 million viewers and a rate of 1.3 among the audience from 18-49, being the lowest in NBC history since 1987 when Nielsen began measuring TV viewing by age.

To see the difference take for example the usual Tuesday 10 p.m. show “Law & Order: Special Victims Unit,” which led with over 12 million viewers and a 4.5 rating.  

The show is about six friends in their 20s who are struggling with their lives having at its center Dylan (Bitsie Tulloch), a character who has a video blog and messes everyone’s lives with her “need” of being honest.

Other characters are Danny (David Walton) and Jed (Scott Michael Foster) who are aspiring filmmakers and best friends. Their love interst will be Debra (Michelle Lombardo). The group is completed by Lisa (Maite Schwartz), a bartender and an insecure actress and Andy (Kevin Christy), a computer wizard.

NBC made a fuss about the show which was announced during the writers’ strike and promoted it.

NBC Entertainment co-chairman Ben Silverman said on Wednesday that the series didn’t live up to expectations, but was “so worth the try.”

He said: “The Web site traffic went up a huge amount, and we continue to try new things and new models. It’s very inexpensive but we hoped for higher ratings,” Reuters reports.

While the Browns continue to negotiate a three-year contract with Pro Bowl quarterback Derek Anderson, general manager Phil Savage protected the team to a certain degree by giving the quarterback the first- and third-round tender offer at $2.562 million.

As of Thursday evening, Anderson, getting feelers from teams in need of quarterbacks, was considering rolling the dice and becoming a restricted free agent to see if there were teams willing to sign him to an offer sheet once free agency starts Friday. Savage, talking to the Cleveland media Thursday morning, said another team could make it difficult for the Browns to match an offer if they want him as a starter, although the Browns’ plan is to retain Anderson and Brady Quinn as their quarterbacks.

The Browns have offered Anderson a three-year deal for about $20 million. Like Matt Schaub a year ago, Anderson would be a popular restricted free agent. The Browns would have seven days to match any offer Anderson signs. Like the Falcons, who traded Schaub to Houston last winter, the Browns could work out a trade different from the first- and third-round choices required if Anderson leaves on an offer sheet.

Restricted free agent tenders have to be submitted to players by 4 p.m. ET or the player becomes a free agent. Thus, for now, Anderson remains the Browns’ starter because of the submission of the tender offer.

The Philadelphia Eagles have released defensive end Jevon Kearse, the team announced Thursday. The move comes as no surprise to Kearse, says agent Drew Rosenhaus.

The team and Kearse had been working to restructure his contract, but to no avail. Kearse signed with the Eagles in 2004 but never really made much of an impact. He had only 7 1/2 sacks in each of his first two seasons with the team and then sustained a major knee injury in the second game of the ‘06 season.

Last season, Kearse had just 3 1/2 sacks and lost his starting job to Juqua Thomas.

“Jevon is still a very talented pass-rusher,” Rosenhaus told reporters over the weekend at the NFL Scouting Combine. “Those guys are hard to find. It’s not a deep year at that position. We think he’ll find a home pretty quickly, once he gets into free agency.”

ProFootballTalk.com reports that Kearse could return to the Tennessee Titans, with whom he was the league’s defensive rookie of the year in 1999.

Last week, the dreams of four young wannabe singers were crushed on Thursday during the American Idol show. Garrett Haley, Amy Davis, Joanne Borgella and Colton Berry were the unfortunate participants who were sent home. The remaining 10 performed yesterday: David Archuleta, Robbie Carrico, Jason Castro, David Cook, Chikezie, David Hernandez, Michael Johns, Luke Menard, Danny Noriega and Jason Yeager.

The young David Archuleta managed to steal the night with a stunning performance of John Lennon’s Imagine, a very, very daring song choice. Few people if any manage to make it sound alright, besides ol’ John, even if they are far more experienced than Archuleta. However, he somehow did it.

“Dog,” judge Randy Jackson said, “that’s one of the best vocals I’ve ever heard on the show. You’re singing with maturity way beyond your years… that was brilliant.”

“That was one of the most moving performances I’ve ever heard,” Paula Abdul continued, on the same note. “You’re destined for superstardom.”

Oh, and even Cowell had something nice to say: “very, very risky to do a John Lennon song, particularly that one, but it worked,” he said. “Right now, you’re the one to beat,” Simon continued.

The other good performance was from gymnast David Hernandez, who nailed good the Temptations classic “Papa Was A Rollin’ Stone,” and won both the viewers’ and the judges’ appraisal. Chikezie also improved, which was noted by the judges: “You looked better, you sounded better,” Cowell said of Chikezie’s strong performance of Donny Hathaway’s I Believe.

Today it will be the ladies’ turn. The Top 10 girls (Kristy Lee Cook, Asia’h Epperson, Alexandréa Lushington, Kady Malloy, Ramiele Malubay, Syesha Mercado, Amanda Overmyer, Carly Smithson, Alaina Whitaker and Brooke White) will compete tonight. Tomorrow night we will find out who the four contestants that will go home are.

The Vote for the Worst campaign has selected this season’s male contestant: Danny Noriega. They still haven’t decided which one of the girls is the worst contestant. The Votefortheworst.com site was started in 2004 to support “the entertaining contestants who the producers would hate to see win on American Idol.”
