NBC Photo/ Heidi GutmanThese days, E Street Band member Steven Van Zandt is known as much for his portrayal of mobster Silvio Dante on The Sopranos as he is for his guitar riffing alongside Bruce Springsteen.  Now, Little Steven's TV career may force him to miss a number of upcoming tour dates with The Boss.

Van Zandt tells Rolling Stone that he has plans to shoot a second season of his Netflix series Lillyhammer -- about a mob boss who relocates to Norway after joining a witness-protection program -- which may interfere with Springsteen's road plans.

"I made commitments before the tour even existed," explains Van Zandt. "We're still trying to figure it all out, and we won't know for another couple of months."

Noting that both Springsteen and his manager, Jon Landau, have been "very, very understanding [and] supportive" with regard to his acting career, Little Steven says, "They're gonna try and bend things around as much as they can.  And then, if they can't, if I gotta miss a few things, I'll miss a few things."

Although the last confirmed date on Bruce's itinerary is a September 22 show in East Rutherford, New Jersey, Rolling Stone reports that Springsteen is planning to schedule a new series of fall North American concerts that could extend into 2013.

Van Zandt tells Rolling Stone until the new tour leg "gets decided and gets announced we can't really figure out what to do."

If Little Steven does have to skip some shows, The E Street Band likely wouldn't have too much trouble picking up the slack, as Springsteen, Nils Lofgren and Patti Scialfa are all guitar players.
