Shock jock Howard Stern's radio sidekick Artie Lange has checked into rehab to be treated for drug and alcohol abuse, according to reports.

The 40-year-old comedian admitted himself into an intensive outpatient rehabilitation program at the weekend, his spokesperson Lewis Kay has confirmed. Lange canceled a series of stand-up shows and appearances, including his pal Bob Saget's Comedy Central Roast on Sunday, to seek treatment.

A source tells the New York Post that Stern's sidekick "felt awful for not being there for Bob, but needed to make his health a priority".

Lange reportedly plans to return to Stern's Sirius radio show following treatment.
